The problem is that the in-kernel driver does not have the 32 bit (for
64 bit archs) compatibility ioctls that megamgr uses.  However, you can
monitor the RAID status directly by looking in /proc/megaraid.  Here's a
script I use:

http://www.iruntheinter.net/files/misc/megacheck.pl-1.0

I run it from cron every 5 minutes.

For managing the RAID, the driver available from LSI's site does have
compat ioctls, but it doesn't build against a 2.6 kernel.  The kernel in
rawhide (for FC3) has the new generation MegaRAID driver enabled (I
haven't tried it yet) and it looks like it also has 32 bit compat ioctls
on 64 bit archs.

I don't speak for anybody but myself - that's enough trouble.
