I haven't look in it carefully. But skimming tells me that the official
driver has more branches for various chips. See the source package:
http://linux.via.com.tw/
Via_drv.so is actually a Linux ELF ABI. Only because it wasn't linked
against any Linux's shared object can it run under FreeBSD simply.
Otherwise, a mechanism like linuxpluginwrapper (Wrapper for Linux
Mozilla/Firefox plugin to work with FreeBSD's native ABI of
Mozilla/Firefox) must be used.
The driver package contains some Linux kernel modules and shared objects,
including libGL.so.1.2.via_chrome9 and via_chrome9_dri.so. Thus, I guess
it is not easy to make the driver function fully under FreeBSD, especially
2D/3D acceleration.
But so far, as I know, it's the unique solution that makes my laptop work.
And I guess it supports more new chips.
I have quite a few products with VIA chipset:
* A laptop with UniChrome Pro IGP (0x3343)
* Motherboard VIA PC2500E with north bridge CN700
* Motherboard VIA PC3500E with north bridge CN896
I can make tests with you.
