The i810 is a graphics chipset embedded on the memory controller, which
was designed for the Intel Pentium II, Pentium III, and Celeron CPUs.  Page 8
of the datasheet specifically says:

Processor/Host Bus Support
- Optimized for the Intel Pentium II processor, Intel Pentium III processor, and Intel
CeleronTM processor
- Supports processor 370-Pin Socket and SC242
connectors
- Supports 32-Bit System Bus Addressing
- 4 deep in-order queue; 4 or 1 deep request queue
- Supports Uni-processor systems only

So no need to clean it up for multiprocessor support.
