So I guess the dynamic data partition is used to store info between reboots and must be smaller than the 16mb used by the RioCar to load the playlist during operation? How hard would it be to get a larger data partition from the Build Brothers?
Repartitioning disks without hosing content is reasonably hard. But the use made of the dynamic data partition isn't very efficient, so we could rearrange it to give more of its space to saved running-order. In fact, we've been threatening to do this for the whole of the v3 era, and it wouldn't surprise me if I'd threatened to do it for v2 final. But I just haven't got round to it.
Without a lot of work (which isn't going to happen) to v2, such a rearrangement would completely bork anyone who switched back from v3 to v2.
Edit: Well, I say "completely" bork; it'd bork their bookmarks and play counts. Whether that counts as complete borkage depends on one's individual bork threshold.

But if one was prepared to hose one's content, could one just make the dynamic data partition larger? Would the player use the extra? I don't remember.

Or if one was starting with a fresh set of drives... Say, 100GB drives for example...

Not at present, no. And the stored running-order comes at the beginning, not the end; changing the code to stat the partition to find the endstop would solve the 28K limit on total fids but not the limit on stored running-order sizes.

Surely changing the code to use only the bytes it needs, rather than all 512 would be a good idea as well. Doesn't each entry only use 32 or 64 bytes (can't remember which).

It's certainly not very much, but the point of using 512 is that it's one sector and can be written atomically; that is, screwing up a write (due to powerfail) can only affect one track's information, not all its neighbours too. But yes, this consideration is probably not worth it, compared to the problems people are having with >256K running-orders. Reducing the FID-dynamic data space and handing the free space over to running-order storage is exactly the plan for, er, sometime in v3.

Actually, that has not been true for most of the past decade or so.. Internally, most IDE drives will rewrite the entire physical track, or a large portion of it, when "rewriting just one sector".

How about Head Honcho Red Coloured Name guy?  (ObOnTopic: Me too. Not that I need the RAM, yet -- I just like having a car stereo that's more powerful than my desktop computers.)

Here's a thought - since we are on the memory redesign, how about CPU - is it conceivable to upgrade to, say PXA255 XScale 400MHz? Then something crazy like video-4-empeg would be within reach

400Mhz ? Even my Pocket PC has a faster XScale than that My 624Mhz Pocket PC is the second fastest processor I own...

PXA255 isn't pin compatible with the StrongARM SA1100 inside the empeg so that'd be one ugly expansion board

What would be cool for a empeg redesign is a pullout screen the a little larger than the size of the Rio Central screen.

Presumably he'd use the same site he did for taking tuner orders.
