Megaraid does not work with 2.4.22

["Krzysztof Olędzki" <ole@ans.pl>]

Hello,

It seems that Megaraid does not work with 2.4.22 at least on
my machine. I don't know when it stopped working because I have never used
this SCSI adapter before. During kernel boot magararid's driver generates
nasty opps. This is the output from oops parsed by ksymoops:

ksymoops 2.4.9 on i686 2.4.22.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.22 (specified)
     -m /boot/System.map-2.4.22 (specified)
