I tried the binary driver from http://upload.aspeedtech.com/BIOS/v10902_linux_freebsd_solaris.zip (the xorg78_5 one) and while it works I would claim it's any faster (certainly not smooth).

I built the source version from http://upload.aspeedtech.com/BIOS/v11001_linux.zip which was a slightly newer version by replacing the source in the usual port, but it behaved the same as the binary version.

I also had an idea to try a last ditch hail Mary and set write combining with memcontrol like the good old days of PCI VESA cards but..
[chumphon 4:05] ~> dmesg|grep vgapci
vgapci0: <VGA-compatible display> port 0xc000-0xc07f mem 0xde000000-0xdeffffff,0xdf000000-0xdf01ffff irq 18 at device 0.0 on pci4
vgapci0: Boot video device
[chumphon 4:06] ~> sudo memcontrol set -b 0xde000000 -l 0x1000000 -o vga write-through write-combine
memcontrol: can't set range: Invalid argument

Although I could set uncacheable (no difference).

Next stop will be obscure BIOS settings I suppose.
