Yes, I think the GL ES support is only very recent.

Eww!

No (not sure what it is) but I am on #fedora-arm and #fedora-mobility

Well there was an update to the toshiba update utility this week so
with luck that's the prep for 2.2, then someone will need to chase

Nope, and esp with only one usb port.
