Just a follow up. I got the card working by disabling ACPI, alltogether. crowd: "I got the card working by disabling ACPI" sorry - Airplane joke Seriously, though. After searching some more I realized that the ACPI was rerouting IRQ requests, and read the FreeBSD page related to ACPI http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/acpi-debug.html#ACPI-SUBMITDEBUG Disabling ACPI is done by setting the following in /boot/device.hints: hint.acpi.0.disabled="1" I tried to disable just a subsystem at first by putting debug.acpi.disable="pci_link" but then the hard drive wasn't found and I had to set the variable at the boot prompt to get running again. So, being this is an ACPI problem, I'll work it through freebsd-acpi@freebsd.org. I'm not brave enough to use the apm device in lieu of acpi because the man page says it can destroy batteries if you're not careful.
