Works fine for me!

Did you check twice that your modified vgabios is actually loaded by
qemu (e.g. via strace)?

Yes, it uses the right rom.

Moreover, does sound work at all with your qemu?
The image I tried [1] issues two beeps after loading (obviously via
direct hw access) - a good way to check general support. Note that one
reason for broken host sound with qemu can be OSS. For that reason I
always configure my qemu with --audio-drv-list=alsa.

Thats a good hint :)
Seems i used to compile qemu without "--audio-drv-list". Since "dsound" and
"fmod" drivers don't compile here (i likely miss some libs in my mingw), i used 
Now i can hear those two beeps with the image you suggested. Tho those are 
thru my sound card and not the hosts pc speaker (even with "-soundhw pcspk", 
but maybe
that option means something different).
With INT 10h AH=0Eh i now can hear a beep too, but it doesn't stop and qemu
