[Wlug] installation of nVidia TNT2 M64 PCI video card

Hi, I have just installed the above card along side my existing AGP video card. I rebooting using the AGP card and ran Yast2 (SuSE's configuration tool) in order to configure it. Everything seemed to go well. I then rebooted the system, went into the bios and told it to boot using the PCI video card. The system detected the card. Just as SuSE started to boot the system hung right after displaying *GRUB Loading Stage2*. Any suggestions on how to resolve this would be appreciated. The system specs: SuSE 8.2 (clean install as of last week) ABIT KT7/KT7-RAID motherboard 800 mhz AMD Athlon 512mb RAM ATI Rage 128 AGP video (old) nVidia TNT2 M64 PCI video (new) Thanks, Mike
