The short set of changes in this patch (against 2.6.15.4)

 * ATOM BIOS support for newer Radeon cards
 * Clean method of detecting and handling disparate BIOS types
 * Radeon RV410/M26/M26GL (aka Mobility X700/FireGL5000) card IDs
 * Default PLL clocks for R420 and variants
 * Handle bogus PLL divider with sane default.
 * All new connector/head detection code that uses bios/firmware 
   defaults whenever possible
 
I can split it apart into smaller logical chunks if desired, but I don't 
think anyone's in a hurry to merge this upstream just yet.  :)  So, 
anyone who has a radeon console and is feeling brave, please give this a 
whirl.  If you are specifying a monitor layout, try it without the 
layout string.  

This is the last of the work I can do on this thing, as I don't have the
hardware (or bug reports/feedback) to develop it further.

Version 5 of the Radeon-Atom patch is attached.  Changes since v4:

 * Completely reworks the old monitor detection code to use the
   connector table.  Cleaned out a ton of cruft.
 * Connector info and LVDS info are pulled on OpenFirmware systems,
   (untested -- I don't have appropriate hardware)
 * Add a module argument to disable BIOS connector tables.
 * Bootstraping the connector table via ddc probing.
 * If user specifies a specific layout, code isn't smart enough to try
   secondary heads if the primary head has nothing attached.  The 
   OpenFirmware code may have similar problems.

4th version changes since v3:

 * ATOM BIOS support for connector detection
 * TMDS parsing for both ATOM and Legacy BIOSes.
 * Additional PCI IDs forall known M26 variants
 * Default PLL clocks for R420 family

3rd version changes since v2:

 * Naming cleanups
 * Merge the OpenFirmware PLL detection into the function pointer mess.
 * Merge the oooold patch's legacy bios connector parsing code, As the
   original stuff didn't really do anything anyway, I don't see the harm.
 * Merge the ooold patch's atom bios connector parsing code, but it still
   doesn't work yet.  It's late and my eyes hurt.

2nd version changes since v1:

 * It has no additional functionality over the original patch, but it's 
   rearranged to be quite a bit cleaner, using function pointers for the 
   atom/legacy bits.

Original Patch:

 * Added PCI IDs for Radeon M26 (aka Mobility X700)
 * Detect ATOM BIOSes, pull PLL/LVDS details from ATOM BIOSes
 * Default PLL divider to 12, and catch obviously bogus results
