It's been a while since I tried to compile a kernel, but I did a good 
effort searching for already existing answers to my situation, so I feel 
I'm in a somewhat unique situation.

As the title says, booting up the kernel hangs after
Mounted devfs on /dev
Freeing unused kernel memory: 144k freed

Magic sysreq gives me (painfully transcribed):

CTRL-ALT-DEL works, so the system isn't totally hung. But no other 
evidence of activity.

I'm using one of these:

Nothing is saved to /var/log/messages from these failed attempts.

I'm trying this from Mandrake 9.1, after having installed 
module-init-tools-0.9.9 that came with the distro. I get the same 
results with gcc-3.2.2 or gcc-2.96, both installed from the distro CDs.

.config and lilo.conf files attached.

Any suggestions, pointers, or other help appreciated.
