[Libreboot] Booting Windows on x60

[hede]

Hi List,

first of all: Is booting Windows XP known broken or working with Libreboot?
(http://libreboot.org/release/20141015/libreboot_bin.tar.xz)

I tried it and I didn't get it.

In case it should work, I'll try to explain what I've done so far:

I installed libreboot on my x60, with success. I can boot Linux from embedded 
grub payload (some debian and arch favours). 

Then I added SeaBIOS (the binary and grub entry) and SeaVGABIOS which starts 
grub from disk. Although text mode is nailed to the top left corner with native 
graphics, this would be fine. But no system boots this way, neither Linux nor 
Windows. It seems that at the moment it tries to switch resolution (kms) it 
stops working. The screen freezes with it's current content.

Then I extracted the proprietary vgabios and added it to the flash. That's all. 
Libreboot is still loading grub in native graphics mode as payload while grub 
loads SeaBIOS and SeaBIOS switches to the low resolution text mode (init 
vgabios?) and then loading grub from disk. This time filling the whole screen 
in text mode. Booting Linux from SeaBIOS is fine this way.

Then I tried starting some old Windows XP, which I need for some old legacy 
closed source app (in very rare conditions). I can choose between normal and 
safe mode. Boot animation seems to be fine (Windows logo in normal mode or 
printing loading libs in safe mode). But whichever I choose, it stops when 
changing screen resolution. Neither in normal mode (intel gpu driver?) nor in 
safe mode (vesa?) Windows can boot. The mouse pointer appears on a black screen 
(with typical "safe mode"-warnings in safe mode), that's it. It stops booting, 
without any error message nor blue screen.

Is this the expected behaviour?

The coreboot wiki says that booting Windows 7 is broken right now, with ending 
in a blue screen. But I do not see that blue screen!?
