Do you have multiple graphics cards in your machine?
Is it something other than a PC?

The patch only allows the use of vidix if the graphics card has its IO 
space enabled which is fairly fundamental for most VGA access on a 
typical PC.

XFree86 does a similar check before using a chip as the primary display 
adapter.

What does the output of "lspci -v -v"  say for the Mach64 PCI device?
The patch will refuse to use the chip unless the output includes 
"Control: I/O+ ..." ( not I/O- )

Without this patch Vidix was trying to use the onboard Mach64 chip which 
had been disabled by the presence of a plugin PCI card. It would just 
hang because the Mach64 chip hadn't been initialized by the Bios.
