I can't remember why I set mine to 64 MB (I'm assuming this is a BIOS setting:
not touched the BIOS in months!).

Mine is an Epia MII-12000. Running the find_revision.sh script from DirectFB
gives me:
Your CLE266 revision number is 17.
To use this value, add the following line to /etc/directfbrc:
unichrome-revision=17
In /etc/directfb I have:
mode=720x576
depth=32
pixelformat=ARGB
disable-module=lirc
disable-module=joystick
disable-module=cle266
no-vt
unichrome-revision=17

How do I fix that? I vaguely remember something a long while back about
something to do with MTRR being broken because two of them overlapped. Not
really delved too deeply because it works at the moment!
