Ok, got F12 on the SB1000, thanks to a vnc install (PGX64 support apparently has some issues, as trying to use local GUI produced a blank display). Upon first boot, I get a console error about the ext4 journal, and the filesystem being remounted in ro mode. The firstboot stuff comes up in text mode (something about not enough memory on the PGX64 for the selected resolution?), but I can't save any settings because the root filesystem is remounted read- only.
