Is yours an 80486SX or DX? That's one issue. I've seen dmesgs from true 
80486 systems (the 486DLC is a 486-class CPU made to work in an 80386 
socket), like so:

I expect you'd need more than 16 megs just to boot, considering the size 
of a GENERIC kernel. Paired down, 16 megs should be plenty. I'm running 
NetBSD 9.2 on an m68030 system with just 10 megs :)

Thanks,
John
