I know I'm missing some hardware, but this is all I could think of.
In fact, almost all common cards are supported. The only one currently unsupported is the DP83815/SiS NIC
Via 82C686 (Seperate from the VT82xx at the moment)
A lot of the sound drivers support compatable chipsets E.g. the Trident & i810 drivers also support chipsets from SiS, ALi & nVidia.
Matrox driver also supports older cards E.g. Millenium
nVidia support for everything from a TNT upto GeForceFX
S3 Virge DX/GX
Trident (VLB & PCI)
A VMWare video driver is available but not yet in Syllable.
The nVidia, GeForceFX, SiS & Mach64 drivers support video overlays. Again it is almost easier to list common cards we do not currently support (Radeon, Intel Extreme, some Savage cards)
You can check http://azaka.nutus.com.ar for a list of "Known Good" hardware with Syllable, although it is not always upto date with the latest drivers & updates.
