Falafel thanks for the dump
mcuelenaere it seems there are some missing files from your latest diff, along the lines of ata-creativezvm.c usb-creativezvm.c and usb-test.c

@Falafel: thanks, link is slow though

Thanks for reporting, here's a more correct diff.

I've been toying with the idea of getting a ZVM to play with the Ti DSP core. How difficult would it be to use the DSP core given the current state of the port?

You read my mind :)
I've already installed the C54xx binaries on my linux box, and tried attaching it to the Makefile but didn't got far.
What I find strange is that I can't find any C54xx binaries in the OF...
But as for getting the DSP core running, that shouldn't be any problem; the code is running quite stable atm; but it's still compiled as bootloader (not that it matters a lot, the HDD structure is in a custom format and so the only solutions are either formatting it to FAT or getting Rockbox to read the format(s) ).
So in short: it is possible. But what would you want to run on it at the current state of the port? I was thinking for getting the audio codecs on them and nothing more, but this isn't yet needed since the port isn't that far.
bgdwie:
I think, initially, rockbox and a few audio codecs should be run from the arm9 core, because the core is quite powerful and most audio codecs can be run well enough from it, and only video and some of the more intensive codecs should use the c54x, for how much work is needed reasons, although, depending upon power consumption, it may be more efficient in the end to have all codecs run from the dsp.
Also, i don't think there is much worry about rockbox running from the flash as this is a lot quicker to startup and uses less power, making it easier to test ;)
also, since the origional firmware allows the device to have dual format drives (part in any format for removable storage, part in custom format for music), it may be possible to put the rockbox datamusic on the removable storage partition so you can run both the OF and the rockbox firmware, that is if you arre contemplating keepign the OF.
as you said: there is no real point in using the c54xx at this stage, and even for the next stage the arm9 will be sufficient for basic audio.
