First of all, I'd like to thank you for taking the initiative to tackle 
this.  I know you're a busy guy, so it means something when you take 
time to work on a lowly video driver. :)

I would like to make one request, though.  When you're working on this 
area of the driver could you please make sure that the driver will work 
if the read buffer and the write buffer are different.  With the 
exception of the MGA driver, pretty much all of the DRI drivers are 
broken in this respect.  That is one of the requirements for being able 
to enable GLX_SGI_make_current_read (which is part of the GLX 1.3 spec) 
in a driver.  Of course, that should be secondary to just making the 
darn thing work. :)
