   Could you please post the output of 'hdparm --Istdout /dev/hda' too 
(we are now in need of more CF identify data)?

   So you're using ide-pci-generic or Bart's new driver?

   Dummy yourself. :-)

   So even the current broken code manages to recognize it as CF... it 
would be espcially interesting to see the raw identify data.
