This is a known issue described in the errata for both the stable release
and the Lenny 1 release . You found the correct way to deal with it,
although you can potentially find yourself in the same situation again if
the "wrong" driver should be loaded first.
However, it seems that two different modules are claiming to support your
IDE drive, which AFAIK should not happen, so the output of 'lspci -nn'
would be very welcome.
