Virtual Framebuffer Support (only for testing!) is just for testing, does not have to do with the basic vga mode selection. However, thank you. If in fact it needs to be checked would indicate a bug or equivalent in the kernel. Having googled before making this reply, i see that there are several problems dealing with the framebuffer's mode selection.
My problems are not that horrific as my machine boot in 80x25 (vga=normal). Others have reported corruption at the tops of screens and hard lockups with the debian kernel. Some have even recompiled without the support. I may try lower resolution and lower bit depth modes possibly-->773, 790 (1024 x 768) or 771, 787, 788 (800x 600).
If yours is working, great! Maybe its a machine or timing dependency thingy. Dunno! But will be listening and checking for kernel revisions.
bout debian but
'bout 2.6.9 for I'm ready to try to patch for DSDT/initrd acpi, bootsplash, and swsusp2.
Well thanx again.
