> Thank you for a considering reply. If you want some hardware for testing, well I have one of those "ominous" Netbooks (apparently HP-Mini 110-4100 with Atom N2600 and GMA3600).
Good to know! Especially a device model. It may be possible to find it on eBay...

Well, the current driver is certainly not yet working for GMA3600 without test.
It needs some work before it can show any activity.
So what we need in addition to hardware is someone who can do this work on the driver
and test every small modification.

Just here. It is still very unlikely that the driver is acceptable by kernel.org
maintainers, even for drivers/staging.

Generally the kernel module is capable of being compiled for different SoC architectures and just needs some glue code for correct setup on a specific SoC. We have it running on several flavours of ARM and partially on one MIPS machine (JZ4780).
