New Revision: 857
URL: http://tracker.coreboot.org/trac/openbios/changeset/857

Log:
The Solaris 9 Fcode boot block relies on the assumption that Sun's OpenBOOT would always interpose /packages/ufs-file-system if 
it existed when opening a disk device. Emulate this behaviour in order to fix Solaris 9 boot. With thanks to Tarl for pointing 
me in the right direction.
