Sorry for cross-posting so much, but this information is relevant to all of the
mailing lists included.

Ok I "solved" my problem, to a certain extent.

Basically the ASUS P5N-E SLI motherboard (nVidia chipset) isn't bootable
with FreeBSD 6.2 RELEASE without going into SAFE MODE (panics after
ohci_add_done looking for a non-existent memory address, if the USB controller
is enabled in the BIOS with "Legacy Mode", i.e. USB Keyboard
compatible), and isn't compatible with FreeBSD 7 at all (kernel can't
map IRQs properly on up-to-date CURRENT and panics in kernel mode during boot).

Strangely enough the 7-CURRENT snapshot ISOs work, but then again it doesn't
setup the OHCI and USB keyboard stuff properly, and I can't get any sort of
input from my keyboard, obviously.

The ASUS P5B-DLX motherboard (Intel chipset) is compatible with FreeBSD 6.2 and
7 though, without any hacks.

Maybe someone should update some documentation on the release notes page for
supported hardware?

Thanks,
