Add the stderr=1 option and post the output result... also, you may want first
to try some later UML (2.6.13.4-bs4 being the latest one).
Also, you will probably need to loop-mount your downloaded root_fs and
fix /etc/inittab to change lines referring to "*getty ttys/1" or "*getty
vc/1" to use tty1, and so on (i.e. convert back the root_fs from DevFS to
non-DevFS); and create /dev/ubd0, ubd1 and so on:
#!/bin/sh
for ((i=0; i<8; i++))
do
# "Traditional" device nodes, ubd0 - ubd7
mknod ubd$i b 98 $[16 * $i]
# "Better named" device nodes, ubda - ubdh
let=$(echo $i|tr '0-7' 'a-z')
mknod ubd$let b 98 $[16 * $i]
# UBD devices support up to 16 partitions per each!
# So we create partition device nodes, which are very similar
# to IDE or SCSI nodes.
for ((p=1; p<=16; p++))
do
mknod ubd$let$p b 98 $[16 * $i + $p]
done
done

Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
