Hi Thank you all for very through answers. The problem was very strange. I had to disable the "ACPI APIC Support" in BIOS. Then I could run grub-install but the computer then lost interrupt to hda (CDROM) and also interrupts to the hard drives. With Grub installed, I could enable this option again and now everything works. Before this change I used to boot with the install CD and make a chroot to the installed system with the dev and proc directories rbind mounted. Then I tried to run X. I got kdm working but if I tried to log in, the computer went into sleeping mode. After the procedure described above, I can switch between console and X mode without any problem. This looks quite like black magic to me but I hope to understand it someday :)
