Works/usable on a 2000 Dell Dimension/PIII@...MHz/128 to 256 MB RAM/i810 graphics running NetBSD 5.1. (with an i810, there are no usable drivers at present...though kdrive i810 might work if I can dig it up...) However, I can't compile vesa drivers with musl. (vesa needs sys/vm86.h to use the BIOS drivers, and sys/io.h for hardware) Also, uvesafb (the universal framebuffer driver) may not work with musl: it relies on a userspace daemon, which uses vm86 or libx86 (which in turn wants vm86, though it can emulate it...)
