"Custom mode lines in xorg.conf will no longer be ignored by the fglrx driver"

Extra funny, because as soon as I use one or more I get:

(II) fglrx(0): Ranges: V min: 50  V max: 160 Hz, H min: 30  H max: 95 kHz,
(II) fglrx(0): End of Display1 EDID data --------------------
(WW) fglrx(0): Only one display is connnected,so single mode is enabled
(II) fglrx(0): Primary Controller - CRT on secondary DAC
(II) fglrx(0): Internal Desktop Setting: 0x00000001
(II) fglrx(0): POWERplay version 3.  1 power state available:
(II) fglrx(0):   1. 398/250MHz @ 0Hz [enable load balancing]
