megaraid with 8GB ram

I wanted to confirm something I saw earlier. I cannot boot with 8GB of ram using the 'megaraid' driver. I switched to the 'megaraid2' driver and it boots up fine. This is reproducible by simply going into yast and setting the hard disk controller module to 'megaraid'. Booting will then fail. I can reboot with kernel option 'maxcpus=0' to get back into the system and then change the driver back to 'megaraid2'. I have no problem using the megaraid2 driver so this isn't a complaint. My system is fast and stable and overall I'm very pleased. I mention this primarily because I noticed the 9.0 installer by default uses the 'megaraid' driver, not 'megaraid2'. I'm using suse pro 9.0.
