Sunfire V480 Installation Trouble: "schizo0: safari error" kernel panic

Good Morning,

Upon attempting to install OpenBSD 5.4 SPARC64 from CD the installer
crashes. This occurs right after the hard drive partitioning and then
after I hit enter to use cd and "cd0" as the install medium.

The system is a Sunfire V480, Quad 1.2 GHz, 16 gigs ram, single 4.5
gig drive to test install on and no expansion cards, just the RSC.

A a horrible picture of the error: http://goput.it/00t.jpg
A type recreation of the log:

"Let's install the sets!

Available CD-ROMs are: cd0.
