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...
