I know of the MTD driver yes, I did actually disable it in my kernel that I built using openwrt 'doh'. Could you give me more information int his regard?
I also don`t know that much about it,sorry. At one point i used an openwrt squashfs? image and that worked but was missing some drivers.
Well I get it all to work, just from USB and not MTD/IDE :)
What flash is being used though, something from the board? Or is the IDE disk used as an MTD device?
As far as i know the flashboard is a MTD device. You have to be careful with write access for the operating system because the write and erase cycles are limited. It is not an real ide disk.
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.
I get a message from the pata_cs5536 driver that IDE is disabled by the bios; and of course no option to enable it.
I use linux kernel 2.6.24 witch is the only one i found that works with the flashboard with ide driver.(maybe a bug in 2.6.24?) I wil send you my config. I use it on a 2.5` laptop hdd connected to the ide port. I wil also send you a working version of coreboot + seabios you can play with. It is configured for ide. You wil need the geode video driver in the kernel to see something. Or you could use a serial connection. Beware there are some issues most notably loading fallback/coreboot_ram takes ~35 seconds so you have to be a little patience while booting.

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 added?
