'my laptop' is a bit too generic to go anywhere w/r troubleshooting

;-)

Can you boot from the original install media, see what it recognized for 
the ATA controller and attached device(s) - then do the same with the 
one with the new kernel - at least as much as you can see.

I'd say you compiled w/o a needed driver except that it sounds as if you 
aren't even getting to where the boot loader can *find* that kernel and 
its drivers.

What did you change for your new kernel?
