Linux guest additions text mode video problems after X server starts -> fixed as of 10 Oct 2011

With Linux guest additions version 4.1.0 and 4.1.2, Linux guests have either corrupt video or blank video in text mode consoles after the X server has started. In the kernel boot options, I am using vga=0x317. When booting to runlevel 3, the consoles all work correctly. After running startx or booting in runlevel 5, you can switch to a text console with left control-left alt F1 through F6. Under Fedora 14 as a guest, the screens are completely black. Under SuSE 11.4 as a guest, TTY1 has distorted colors and the fonts are 4 times larger than they should be, and TTY2 through TTY6 are black. When exiting from the X server after startx, the console is unusable. When shutting down or rebooting the guest machine from runlevel 5, you can't read the console shutdown messages.
You can switch back to the X server with left alt F7, and the display is fine there.
Reverting back to 4.0.x guest additions do not exhibit this problem. I have verified that there are no problems switching back to text mode with version 4.0.8, 4.0.10, and 4.0.12 guest additions under VirtualBox 4.1.2.
