Maybe a pcie Radeon HD6450
ummm, they are all big-monster-cards, with big heat-sinks and often with a big fan cooler; I'd prefer something small, with
PCIe 1x connector, something passive cooled, and possibly without an heat-sink at all.
Isn't possible? ... well, something like the "
Gigabyte GC-IVA" (hope this is the correct vendor/model), which seems hard to find, and I don't know anything about its support for Linux. But it's exactly what I'd like to have.
Look at this beauty of simplicity!
As comparison, look at the (old)
ATI-Rage-XL8; look how tiny, simple, and beauty it was! It also used SDRAM as video memory (which is hackable, but hey? this is for a crazy idea), and its kernel driver is still very very simple. Unfortunately it's not PCIe. I wonder it will work with a PCIe-to-PCI adapter.
I am also curious about the "
Matrox Millennium G550-pcie". Last time I played with an MDA kernel module for the G400 series it took me over 2 years to hack it so that both video channels worked fully on an embedded-SBC, so ... I don't know. MDA1 (for Matrox Millennium I / II) was a great piece of kernel code, MDA2 (for Matrox Millennium G400) ... was a nightmare. But I don't know anything about that G550-pcie. I've never tried myself
I have ZERO experience with AMD and Radeon video cards.
