I can login with ssh. suspend/resume does not change the situation. /dev/fb0 does not exist.

DRM and non-DRM configs use different modules.
By using the DRM config, you disable the glamo-fb module, responsible for the display, in favor of the DRM/KMS ones.
However, om-gta02-2.6.32 doesn't contain those modules, and you end up with nothing to handle display.

By the way, om-gta02-2.6.32 containing gta02_drm_defconfig is useless and misleading, since the corresponding modules are not there.
