Try adding “nomodeset” to the kernel boot options. (Just enter that at the boot menu)

But 11.2 is very old and not supported any more since more than 2 years. Why don’t you try with a newer version instead?
The current one is 12.3. You can download it here: Download openSUSE 12.3

If you do want to stay with 11.2, you should consider to add the “Evergreen” repo:

Evergreen will support 11.2 until Nov. 2013.
