Hi,

I have a thinkpad A21p with, according to Xfree, the following chipset:
"ATI Rage 128 Mobility LF (AGP)" (ChipID = 0x4c46)

More specifically:

(II) R128(0): Primary V_BIOS segment is: 0xc000
(--) R128(0): Chipset: "ATI Rage 128 Mobility LF (AGP)" (ChipID = 0x4c46)
(--) R128(0): Linear framebuffer at 0xf8000000
(--) R128(0): MMIO registers at 0xf0200000
(--) R128(0): VideoRAM: 16384 kByte (128-bit SDR SGRAM 1:1)
(**) R128(0): Using flat panel for display
(II) R128(0): Panel size: 1600x1200
(II) R128(0): Panel ID: LG.PHILIPS LP150U1-A2   
(II) R128(0): Panel Type: Color, Single, TFT
(II) R128(0): Panel Interface: LVDS
(II) R128(0): PLL parameters: rf=2950 rd=65 min=12500 max=25000; xclk=10500

I tried  both XF 4.1  and 4.2.1,  and in both,  XV support is  buggy: it
shows the left half of the picture stretched in size (about doubled).

1) Do you know who the current maintainer(s) is/are?
   (The docs still point to faith  & kevin @ precision insight, but they
   both haven't worked at VA Linux for a while (I know, I was postmaster
   :-))

2) Can I provide any help on getting XV working on that chip?

If that helps:
