The latest driver available is 6.2.1 available from here:

http://people.FreeBSD.org/~gibbs/linux/

The 2.4.7 patches will likely work for your mandrake setup.
For this particular problem, I don't think it will make much
of a difference.

Parity errors are hard to "create" in the driver.  They almost always
indicate a problem with your cabling or termination setup.  If you boot
with "aic7xxx=verbose", the termination settings will be displayed
at boot which will unveil any problems on the controller end.  What
are you using for termination on the HP changer?  How long is the cable
from the machine to the changer?
