executing ioctl 0x80 megaraid2-2.10.7

Greetings,
  In the past was using my utility to get status information from the megaraid device using ioctl 0x80. 
When I installed a new driver megaraid2-2.10.7 and try to execute same ioctl, I started to get kernel panics. I'm using AS 2.1 with kernel 2.4.9-e.49smp . I'm kind of stumble because 2-2.10.7 suppose to convert old ioctl to the new format and feel up all needed address.

Did anyone ran into this problem before ?

Thank you very much in advance !
