megaraid not working in 2.6.18

hi,

I have two servers with AMI megaraid.
They both runnig 2.6.11.*

I want to upgrade to 2.6.18. The problem is: the driver does not work anymore.

If I try the new driver, the kernel freezes after I see a stack trace dump. It is OK, I read somewhere that I should not use this new one as it does not support my old cards.

However the legacy megaraid drivers does not work either. I get unknown-block-device error when the kernel tries to mount sdaX. I do not even see the megaraid driver coming up! no detecting messages like in 2.6.11

This page: http://linux.dell.com/storage.shtml#megaraid lead me to this list.
