The attached patch fixes compile errors in imm.c in 2.5.1pre6.  At boot it 
will detect the drive however if a disk is in the drive I get an oops (see 
oops1.log).  If there is no disk it will boot just fine.

When I run 'eject /dev/sda' after I insert a disk in the drive I get an oops 
(see oops2.log).

Please give me some feedback on what can be done to fix these problems.  I 
can also do other tests and provide more information if need.

Thanks,
Rich
