I have A Orchid Kelvin 64 VLB which uses the 5434 chipset.

I get the screen corrupted in 16 and 32 bit modes.

This corruption is probably caused when I enable option "linear" which
is required for 16 and 32 bpp modes.

Can anyone suggest other options to try to get this card working?

YES!!!

I finally got this to work.  Here's how:
1.  Add the following lines to your /etc/XF86Config
        Under "Device":
                MemBase 0xA0000000      <= might try different values
                Option "mmio"
        Under "Screen":
                You need a seperate display section for each bpp i.e.,
                        Subsection "Display"
                                Depth 16
                                Virtual 1024x768
                                Viewport 0 0
                                Modes "1024x768"
                                Option "linear"  <= IMPORTANT!!!
                        EndSubsection
