Ndis driver causes kernel problems on boot

[Mark Moellering]

  I created a driver for my rtl8187 SE in my MSI Wind netbook using ndisgen.
I placed the driver , rtl8187Se_sys.ko in /boot/modules

I added rtl8187Se_sys_load="YES" in /boot/loader.conf

I can kldload rtl8187Se_sys and everything seems OK.
If I reboot, however, I get the following error during boot (truncated 
to what I think is the relevant info);

Fata trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address    = 0xf00032d4
fault code                     = supervisor read, page not present
...
current process            = 12 (swi4: clock)

I am a little lost at this point.  If I start in bootloader prompt mode, 
I type;
OK> unload
OK> load /boot/kernel/kernel
OK> boot

and everything works fine.

Any and all help is appreciated.
