Well I get it all to work, just from USB and not MTD/IDE :)

Well the docs mention there's 2 ports, and it is either flash, or IDE 
based on a bios setting. The real question is, what is the mini-IDE port 
wired too. I'll look up the specs of the chip and try to follow some 
lines and maybe I can see. Probably not.

I actually got a Transcend 1GB Disk on Chip module; It has firmware and 
everything, I think it's like a compact flash device, but since I 
haven't been able to access it via the IDE port; I don't know. If it is 
an MTD device, I suppose hdparm/smartctl won't work on an mtd device.

Hmm, maybe 2.6.24 does do something? I'll try to confirm it on 2.6.24 
(maybe it's only an option?) and then bisect/diff with a more recent 
kernel to see if they changed something.

That coreboot image sounds _Very_ interesting, would I be able to build 
it myself? That file you sent me, is coreboot +seabios elf image 
combined so 'ready' but without any video output until the kernel is 
loaded? So the only way to choose a different boot option would be via 
serial console? How about USB keyboard support; that in there as well? 
As our S*0's only speak usb and not ps/2 :)
I guess i just flash it and I'm 'done', no VSA or video rom needs to be
