I am still very eager to get the external crt display working.  One 
possibility was to configure X so that it could drive the crt.  Luca's 
comment and some lines in the log make me think there is a chance, but I 
still don't know how to get it to work.  Do I need a change to the config?  
Must the external monitor be connected when X starts?  I copied some sections 
from the log that make me think it might work if someone can point me in the 
right direction.

Another possibility would be to figure out how to fix the keyboard hotkey 
FnF8, which should turn on the crt but is buggy, or how to fix i810switch, 
which activates the crt by writing to a location in /dev/mem but drives the 
crt at a frequency that is out of range.

There is some information about i855 graphics registers in this datasheet

http://developer.intel.com/design/chipsets/datashts/252615.htm

Could this be used to fix i810switch?  Could we program SXGA+ resolution 
without relying on the BIOS?  Would disassembling the BIOS help?  Or would we 
need better documentation from Intel to do it?  I would be very interested in 
helping with an effort to work on these issues.
