this is not about mode settings, it's about how the Xorg xserver
maps framebuffer and registers. Xorg from lenny tries the old method,
which fails on the C8000 for some reason, I haven't understood, yet.
Xorg from sid only uses mapping of the pci node from sysfs, which uses
pci_mmap inside the kernel. And the current upstream parisc kernel
has not support for mapping via pci sysfs nodes.
