What crash? Do you mean a panic, or a drop to single-user mode (expected, as your /etc/fstab entries will be wrong), or a trap? > If I boot off floppy and do the fixit disk, I can mount /dev/wd2a > properly...so why can't I seem to get it from the 'boot:' prompt? Misunderstanding on your part. The number in parens in the wd(2,a)kernel string means "BIOS wd disk unit 2". But in your kernel configuration, wd2 is the first disk on the second controller. So you want to boot wd(1,a)kernel, and mount /dev/wd2. This may actually be problematic for the boot code; you may have to regenerate your kernel so that wd1 is actually on the second controller so that the BIOS and wd unit numbers match.
