I'm trying to install NetBSD 1.5.2 for the first time on an AlphaStation 
500/333, from floppies.  When the kernel on the floppy tries to boot, it 
panics immediately with:

	panic: tga_console(7, 0): unknown board configuration

Below is the boot-time output from the Digital UNIX 4.0F that's currently 
running on this machine.  Any thoughts?  (Note that there are two display 
cards, tga0 and tga1 in this machine.)
