NetBSD 5 having trouble with NICs

["Michael D. Spence" <spence%panix.com@localhost>]

I'm trying to install NetBSD 5 on an older HP to 
replace my really, really old NetBSD 2 system on my 
really, really old 166MHz pentium.
 
I downloaded and burned the NetBSD 5 iso image and 
ran the install.  Things were moving right along until I 
started looking into setting up the network.
 
 
dmesg reports:
 
fxp0 at pci2 dev 8 function 0: unable to map device registers
ex0 at pci2 dev 9 function 0: can map i/o space
 
I'm guessing that the GENERIC kernel isn't going to work for
me and that I need to download the kernel source and hop to
it.  Where can I learn about options for the kernel rebuild that 
might be useful in this situation?  
 
Also, is there a quicker way?
