Just as a (possibly related) side note:
The 4.2 Beta CD does not boot on a system that has a MultiTech
MT5634ZPX PCI (aka ActionTec 56k FAX PCI Modem) modem card (yes, that
one has a controller and is supported by FreeBSD). Interestingly, once
the system is installed, the card can be replaced and the system will
boot using the generic kernel...
