Ok, got the master branch from git...

A couple of stupid questions:

* why do the guts of sil164_mode_set() not do anything?

* and what should sil164_mode_valid() be doing (optimally)?

* how do you know if the hardware can handle 24-bit or full-pixel
   per cycle mode (instead of half-pixels)?

* how is the interrupt on HOTPLUG handled by the GPU code?

* why set the I2C address as 38<<1 (SIL164_ADDR_1<<1) instead
   of just 0x70?

* and should be I2C address reside in _I830DVODriver, or in
  I830I2CVidOutputRec or SIL164Rec?  It seems to be chip-specific,
  not board-specific...

* what are the chances of _I830DVODriver becoming _Xf86DVODriver
   instead?

* ditto for I830I2CVidOutputRec...

Thanks,
