As the experimental version needs so many changes, how about the
attached patch to fix the issue for lenny?
It modifies nothing but adds another RADEON_CLOCK_CNTL_INDEX to 0
setting, like it is already there for CHIP_FAMILY_RV410, just more
limited (not within RADEONRestoreLVDSRegisters but only after one
specific call of it and with more guards) and changes nothing else.
Thanks in advance,
Bernhard R. Link
