Thabks, I missed that. I will add it to the patch, as well as the VN1000 patch.

There's an issue with memory detection, but that's not surprising as the driver is poking at registers that might not be the same as for previous chips.
How many video ram is your board supposed to have ? Check the bios or the log from the working driver. Btw, could you provide the full X log with the driver from VIA/S3G ?
Also, could you try to change the amount of video ram in the bios and check if the value reported in the X log from patched openchrome changes accordingly ?
