Windows NT doesn't boot after upgrade of guest additions to 3.0.6 => Fixed in SVN/3.0.8

The video driver of the VBox Guest Additions 3.0.6 seems to be non-WinNT 4.0 compatible. Windows NT bootet fine after I upgraded the Host to 3.0.6. But after the upgrade of the Guest Additions from 3.0.4 to 3.0.6 it says:

STOP: c0000263 {Driver Entry Point Not Found} The \SystemRoot\System32\DRIVERS\VboxVideo.sys device driver could not locate the entry point MmGetSystemRoutineAddess in driver ntoskernel.exe.

Note: Even VGA-Mode doesn't boot anymore.

Thanks for the report. The fix will be available in the next VBox version. Meanwhile please try fixed additions:  http://www.virtualbox.org/download/testcase/VBoxGuestAdditions-r52409.iso

I was able to make Windows NT boot again by deleting the VBoxVideo.sys file. The video driver of the r52409 additions works fine.
