Interesting. Is it possible to change the IRQ to something useful in UKC? The boot log seems to crap out at a certain point and starts from the top, overwriting the first twenty odd lines at a horizontal offset.
Precisely between 'vgafb0 at pci0' and 'wsdisplay0 at vgafb0'. But could be a wsdisplay issue that could be fixed with some kernel setting.
