I don't know if the new 14" iBooks also have that chip, so they might also be supported. The chip identifies itself as "RV350 NV" (pci id 0x4e56), revision 0x80. Apple calls it "Snowy", xfree86 names it "ATI FireGL Mobility T2 (M11) NV (AGP)". So, we seem to be lucky here: The suspend-code for the M10 (which also is a "RV350 NV") works flawless for that chip.
