I have an older video card (lspci says)
ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE]

Here is the output of radeontool regmatch TV_DAC_CNTL:

You also said you wanted to see the vbios, but I can figure out how to get that
information. Is that something I need to look at during boot time, or is that
something I can get any time?

Please let me know if I can do anything else to help. I am by no means an
expert, but I can test stuff out if I'm given good enough instruction.
