Excellent!  Two other questions (not necessarily related):

A) Is it (or will it ever be) possible to run dual head 
using two different cards (like radeon & riva-tnt2)?  I know 
there is still much work to be done, but I was curious if 
this was even remotely possible.  Sorta hate to let a good 
video card go to waste if you know what I mean :-).

B) Does anyone have a painless, yet precise way of 
generating modelines for fb.modes if you are using 
XFree-4.2?  I only ask because the XFree modelines are all 
determined by i2c DDC probing, thus there are none in the 
XF86Config file.  The modeline output captured in the log 
XFree.0.log is not the same output which modeline2fb 
expects.  Anyhow, I've tried using some of the information 
in the log, but I always get funky results.  I may be 
looking in the wrong place, but the documentation for both 
the fbdev kernel drivers and the X drivers are sorely out of 
date, so please excuse me if this is a question that has 
previously been answered.  I just need some formulae to 
convert values between what shows up in XFree.0.log when i2c 
DDC probes for the modelines and what needs to go in 
fb.modes.  Thanks in advance!

Cheers,
Nicholas
