The onboard 3COM 3C920B on the Asus P4R800-VM motherboard has a PCI card ID of 9202.  The xl driver only supports the 9201 variant.
Boot FreeBSD on an ASUS P4R800-VM motherboard.  Note the lack of any detected network adapters.
For a quick and dirty workaround, I changed line 686 in /sys/pci/if_xlreg.h to use 0x9202 instead of 0x9201 for the TC_TORNADO_10_100BT_920B define.  The proper fix probably requires someone smarter than me to look at /sys/pci/if_xl.c as well.
