Comment 10 for bug 942846

I was able to reproduce basically the same symptoms, but the workaround is slightly different. I've an amd64 with NVIDIA Corporation G92 [GeForce 9800 GX2] (rev a2). The _only_ way that this system will display the encryption password prompt is if you boot without "splash" in the kernel command line. I can alter which VT the password prompts appear in by changing the vt.handoff number from 7 to 1.

If splash is enabled then vt 1 comes up completely blank. Switching to vt 2 etc produces a single unblinking cursor.
