Description Benjamin Herrenschmidt 2005-08-22 20:05:27 UTC 
The radeon driver has a bug in the code parsing the connector table from the
BIOS, causing it to usually only ever get the infos for the first connector.
This is due to an incorrect loop exit condition. The attached patch fixes this
the simple way. That parsing code is still a bit dodgy as the connector table
can potentially get more complicated than a single list according to the spec,
but I've never seen that case happening in practice.
This should fix DVI detection in some cases

might as well get this in.  I'll test and commit soon unless some one beats me
to it.
