Kickstart via ks=hd not working

[Phil Oester <kernel linuxace com>]

When using ks=hd: on the command line, I get an error that the ks.cfg
file can't be found, but if I hit enter on the same path, it works the
second time.  It seems to be due to the scsi drives not yet being ready
when kickstart first looks for the file.

>From the logs:

Any ideas?  Some need for scsi_wait_scan here perhaps?
