They followd a rule to add B, C, ... when it's a revised, remodeled or
NetBSD has accelerated PMAGB-B driver for long time. The driver has

PMAGD has a variation across 8bpp only, 24bpp capble and plus Z-buffer

Design of SFB ASIC is well described in Digital Western Research Lab's
paper. I wrote dev/tc/sfb.c code by using it.
