I am running the newer Elan SC520 embedded. I also can boot our SC400
development board. Note that the SC400 must not have code generated for
any CPU newer than a '386. This is because it _seems_ like a '486 but
it does not have a FP unit. It may be croaking on the first FINIT that
the kernel startup does.

Compile your kernel as a '386 with FP emulation and it should work.
