I have found a work-around: add


to /boot/loader.conf.

Via http://numeri.campus.luth.se/~k/T20/ you can find the info from my computer
dmesg.acpi - ACPI enabled (panics when card is inserted)
dmesg.no_acpi - ACPI disabled (works)
dmesg.acpi.sysresource - with debug.acpi.disabled="sysresource" (works)
devinfo-r.sysresource - booted with debug.acpi.disabled="sysresource"
devinfo-r - booted with ACPI enabled
panic.msg - the panic message when booted with ACPI fully enabled
kgdb.out - scripted kgdb output

All this is with 5.3-BETA5

I hope this info helps.
