Boot page fault - alternative kernel needed?

I have an old laptop that I am finally trying to get FreeBSD installed on.  It was recently running Linux just fine, 
but I am having a tough time getting FreeBSD installed on it.  Here is the error I get when booting.  I have typed all 
that is visible on the screen when it crashes.

# Begin

isa0: <ISA Bus> on isab0
atapci0: <Intel PIIX4 UDMA33 controller> port 0x3000-0x300f,0x376,0x170-0x177,0x

current process        = 0 (swapper)
trap number            = 12
panic: page fault

# End

So, my question is: Is this the UHCI driver failing to load (happens at this same point every time I try to boot it)? 
Is there any way around this? Possible using a trimmed down kernel to boot?  Any suggestions?

Thanks in advance,
