I don't clearly understand what you mean.  In any case, the output of
`lspci' here is the same as yours (once the SunPCi board has been
removed), except for the SCSI controller which I don't have (see below).

In the meantime, I found bug #384450 [0] which addresses this very
issue:

  The bug is that the Xorg PCI drivers fail to properly decode the I/O
  port ranges for any PCI cards (not just video cards) having I/O ports
  that have start or end+1 addresses that aren't 16-byte aligned.
  
  [...]
  
  Practically-speaking, the result is that adding unrelated, otherwise
  perfectly Linux-compatible hardware can make accelerated X completely
  non-functional.

The proposed patch should have been part of Xorg 7.1 but that doesn't
seem to be the case.  If no Xorg release occurs by the time Etch is
released, then perhaps it should be applied to the Debian package?

Thanks,
Ludovic.
