Does this mean that's there is no way to run with a 24 bit depth
on a Vis-EG?  I have been playing with this but I haven't had any luck.
There doesn't seem to be any way to change the depth from 8 bpp on a
c3k using the PDC (there is user defined parameter set but it's not
clear how it can be set other than possibly with sam under hpux).  I
tried "stifb=bpp32:" but this didn't have any effect on the reported
1280x1024-8 config in dmesg:

STI GSC/PCI graphics driver version 0.9

stifb: Unsupported gfx card id 0x35acda30

The linux config has

CONFIG_FBCON_CFB8=y
CONFIG_FBCON_CFB32=y
CONFIG_FBCON_STI=y

Oh, I've one other X config problem.  The usb mouse stops responding
at logout from kde.  If I restart the X server with <alt>E, functionality
is restored.  I don't believe that this is a kde problem.  Anybody have
a solution?
