No, there aren't any pre-vap entries.
Attached you find my rc.conf, dmesg output and I managed to get a proper
kgdb output of the panic.

I don't know if that could be related, I need to change the IRQ settings
for the cardbus to get my card recognized. So I have this in /etc/rc:
pciconf -wb pci0:0:30:0 0x1a 8

When I am fast enough and insert the card shortly after the partitions
are mounted, everything runs normally, wpa_supplicant gets started and I
get connected to the wireless net.
