linux-2.1.90 PATCH: kmod hangs in initial ramdisk

In Linux 2.1.90, the "linuxrc" program in the initial
ramdisk is run before the kernel kmod thread has been created, so
it hangs as soon is it does anything that causes request_module()
to be called (for example, by loading the scsi disk module, which
now does a request_module("scsi_hostadatper")).

Here is the patch that move the start of kmod to before
the running of the initial ramdisk. It works for me. I am writing
this message from a machine running 2.1.90 that had its disk drivers
loaded by an initial ramdisk.
