Thats the one qemu is using. Also available from

Almost correct. You need VGABIOS-lgpl-latest.stdvga.bin

There is some work in progress to put the vgabios included in
seabios.git into better shape, which hopefully gives us a vgabios which
does (a) does not require dev86 to build and (b) is almost completely c
code not assembler and thus much easier to hack.
There is a communication channel between seabios & qemu already
(fw_cfg), that could be used by vgabios too to get non-standard screen
resolutions configured at runtime.
cheers,
Gerd
