I used the following patch the print the table values
(so I skipped the modification of the actual values, only printing
the BIOS values)

                    if (i == 0) stride += 10;
                    else stride += 6;
                }

and got for about 25 cards the same result:

(II) RADEON(0): PLL parameters: rf=2700 rd=12 min=20000 max=40000; xclk=20000
(II) RADEON(0): DFP table revision: 4
(II) RADEON(0): tmds entry 0 value 0x1fa0191 freq 15500
(II) RADEON(0): tmds entry 1 value 0x1fa0191 freq 20000
(II) RADEON(0): tmds entry 2 value 0x4e20000c freq 0

Hope this helps. Please let me know when I can give more info
