Problems with Optibase VideoPlex XPress (zoran)

Hi

I get a "No such device" error when tryign to use Optibase VideoPlex
XPress card in Linux. The card works correctly in win2000.  The driver
loads fine. Any ideas what's wrong?

Kernel is 2.2.18 patched with bigphysarea patch. zoran drivers are the
ones downloaded from www.optibase.com, which are 0.6.2 with Vaddis.c
added.
