FYI - Maybe it could be added as a TID?

On our Dell Optiplex 260's, when I would start "Zen Maint Mode" at the point
the SUSE splash screen should apear, I was getting the following error: "You
Passed an Undefined Mode"

Turns out that this occurs when the BIOS setting "Onboard Video Buffer" is
set to 1MB instead of 8MB. When set to 8MB, the error goes away.
