[radeonhd] Radeon Mobility X1400 support

Hi radeonhd, as requested per the Xorg messages, here's the log from my card. I quickly patched 2 lines in order for it to be more useful. My machine is a Core 2 Duo laptop (Lenovo T60) running NetBSD 4.0_BETA2, with modular-xorg 1.3 from the pkgsrc ports tree. What would it take to support the M54 chip, so that I can get an output on the panel? HTH, -- khorben
