Toshiba Libretto 70CT won't execve

Description of problem:
On a Toshiba Libretto 70CT, the 2.4.18-3 kernel boots up until freeing
the extra kernel memory. After this, the execve to /sbin/init returns
success, but /sbin/init does not run.
The Toshiba Libretto 70CT has a 586 with MMX processor and 32MB of
memory. It runs vanilla Redhat 6.2 fine. It will not run Redhat 7.0
or Redhat 7.3 (2.4.18-3), so the bug has existed for quite some time.
The problem is that, on boot, I see:
Freeing unused kernel memory: (some number)
...hangs forever here...
I tried having the kernel run the shell instead, but that did not work
either. I also recompiled /sbin/init to print out a message to stderr
first off, but nothing appeared. Putting the disk into another 686
machine runs fine.
I recompiled the kernel and started adding printk debugging statements.
I found that search_binary_handler() (from fs/exec.c) returns success.
At this point it is clear to me that I am not going to get any farther
with printk statements.
I also tried to make an a.out executable (rather than an ELF), but the
ld in Redhat is not compiled to create one, and I was unable to figure
out how to configure the recompile of ld to make it do so. If someone
could send me an a.out-style executable of some sort, that would be the
next obvious test.
I will be out of town from 2002-08-21 to 2002-08-29.
