Strange, It is included in the kernel i build too. Could you send me the
.config of your 2.2.20 kernel, as well as the output of lspci with the
-n option to get the device numbers. I remember a recent discussion on
the linux-fbdev list about some strangeness with Mach64 pci ids, maybe
it is related.
