I've got very similar problem. I managed to install Mandriva Spring on my computer (Athlon XP 3200+, Radeon X800Pro,ASUS A7V880 mobo, Maxtor ATA-133) without problems. But when I tried to boot for the first time, nothing would happen just after I chose the boot mode (normal). Then I added some options to kernel boot parameter
noapic nolapic acpi=off
and that helped a bit, but now booting process stops just before displaying KDE login menu. The screen turns black, but remains on, and nothing would happen.
