Hello Alan,

  on ALi here devices are now recognized successfully. Some excerpts from the

The improvement from the previous patch is that the cdrom is seen as "sr0" now 
(instead of "sdb") and the bogus warnings have disappeared. Performances are 
still low, as expected. Please tell me if I can do something else.

Thanks and regards,

  Francesco
