  Yeah, exact same card. I will try the LCD patch, does X work with it?
  For me the reason for using FB is X, it wont work otherwise. Why? I don't
know..
  Will take this up with X-Pert..!

  My experience is almost the same with the following board:

  01:00.0 VGA compatible controller: ATI Technologies Inc Rage Mobility P/M
AGP 2x
  +(rev 64) (prog-if 00 [VGA])
          Subsystem: ATI Technologies Inc Rage Mobility P/M AGP 2x
          Flags: bus master, stepping, medium devsel, latency 64, IRQ 9
          Memory at e4000000 (32-bit, non-prefetchable) [size=16M]
          I/O ports at c000 [size=256]
          Memory at e6000000 (32-bit, non-prefetchable) [size=4K]
          Expansion ROM at <unassigned> [disabled] [size=128K]
          Capabilities: [50] AGP version 1.0
          Capabilities: [5c] Power Management version 1

  The PCI id is Ox4d4c, and you?

  e.g. I got the famous encrypted white screen with at least 2.4.9 but
  now with 2.5.69 + LCD patch posted recently, it's much better. I get
  half the screen duplicated verticaly but with correct resolution.

  I guess this is a modesetting problem?

  You should try the 2.5.69+patch...

  Note that I had to disable everything else but the ATY driver (VESA,
VGA16,
  framebuffer virtual).
