Well, I will make it in the next days. Unfortunatly, the X fbdev driver
does not work. Probably it is a inconsistent between viafb and fbdev.
Doesn't matter. I have find out, that the TinyX Xfbdev-Server works
great :D

No problem. But there are many calls to devices, which the epia-ml not
have. I think, that makes Linuxbios a little bit slow or there are other
dev_find_device calls with false device IDs :D. I will try to remove
these sections before I create a new target.

That's right. I have looked again and again at the code and it seems it
is garbage, only. But I'm not sure.

Not, if the write_protect_vgabios function works :)
I have read somewhere in the net, that newer epias have a new designed
CLE266 Chipsets. It could be the reason for the different device IDs
In the X source code I have found somewhere:
1106_3122 = VT8623 [Apollo CLE266] integrated CastleRock graphics
1106_3123 = VT8623 [Apollo CLE266]

Good idea.
