i have the same problem (last tested using 2.0.5 and a 2.1-SNAP) with
ide - the dump works if i'm in text mode but not if i'm in X (it's a
winner 2000 pci card) using the XF86_S3 server but it also works if i
use the XF86_VGA16 server ??? - in the S3 case it simply hangs there
for ever with the hd light on (IDE)
