[Fedora-sparc] Issue with SBUS ESP?

Good afternoon. After letting the SB1000 F12beta install percolate for a while, I decided to take my spare SCSI DVD-ROM drive out of the second SB1000, and put it in the E6500. After the 20 minute boot up wait on the E6500 (takes a right long while to boot 17CPU's and 20GB of RAM on one!), I was able to boot the F12Beta ISO, issuing a 'linux vnc vncpassword=xxxxxx console=ttyS0,9600' and it started coming up. However, once the initrd has come up, it can no longer find the DVD. Since I'm on a serial console, it's difficult to see what's going on. And copy/paste from GTKTERM I've not figured out, yet.... I try to load the Sun ESP driver, but it still doesn't find anything. Any parameters I need to pass to the driver for the SBUS ESP on the E6500 to recognize the DVD?
