My Number Nine Imagine Series II card with 4MB of memory is not correctly recognized in the version of XF86_I128 distributed with RedHat 6.1. The problem is present both with XF86_I128-3.3.5-3.i386.rpm and XF86_I128-3.3.5-15.i386.rpm. Reverting to XF86_I128-3.3.3.1-49 version of the package distributed with 6.0 fixes the problem.
