I too have exactly same problem and scree0 output as Robert McKee!
I run Jaunty 64 (all updates installed) on my old Medion MD96400 that has an AMD64 Turion Mobile 1.6GHz CPU and 512 MB ram.

I saw the tip about removing the "splash" and "quiet" boot options and
adding "vga=791", so I did a more thorough test, trying all combinations
of vga=791, splash and quiet (0=off, 1=on). My results were:

V S Q
0 0 0 - Works
0 0 1 - Works (My new default options)
0 1 0 - Does not work
0 1 1 - Does not work (The default options)
1 0 0 - Works
1 0 1 - Works
1 1 0 - Works (!)
1 1 1 - Works (!)

So it seems that there are two workarounds:
- Without vga=791, splash has to be disabled for it to work.
- With vga=791, it does not matter if splash or quiet are enabled or not.

The boot option vga=791 means 16 bit 1024x768 kernel video mode
according to http://www.pendrivelinux.com/vga-boot-modes-to-set-screen-
resolution/. Since my screen is 1280x800, this pushed the splash screen
out of place, so I chose just to disable splash without adding vga=791
as my new default options.)

My startup time was the same in all the tests. (43 seconds +/- 1 second)

I hope someone can figure out what is wrong so we don't have to disable
the splash screen for shutdown/reboot to work :)
