Certainly, even if the FreeBSD report's feedback is not very optimist
on this particular mainboard (mainly because some of the main components
are not _yet_ tested, as PCI-E or onboard Gig-E).

Not having a serial port may be a problem.  Is it possible to use the
USB port to act a serial for console access?

Since we certainly will use an other ethernet card on bus PCI, the last
point is annoying but not for the moment (we doesn't use Gig-E yet, just
100Mbps (as with nve(4), it seems)).

Thank you.
