Hello Voonskibular .
First you very welcome and happy that you like the U.E Distro
About the Ubuntu BOOT screen = well it is Ubuntu sabotage like the issue with Ubuntu tweak clean up,scrip clean up
and so on.
when I first see this BOOT screen I understand that any Update on the system make one more operation from the
other side of the system - write the BOOT from the start and add Ubuntu to be the Default BOOT screen.
And the main issue with the Nvidia IS NOT BUG = this is Ubuntu sabotage!
So I will say that ,on our Team the PPL that has the Nvidia Cards Upgrade the Kernel once again to solve the issue.
And in this point of time myself has upgrade it too to the RC1 of 2.6.35 = The Ubuntu 10.10 system.
And I did not have to do it because I have the Intel Video Card.
But we all do all the tests workaround for all the Video Cards for you all (Part of our work right

),
So here is my solution for you to try on.
Get the RC1 for your Architecture machine and install it at the same process like you made my Guide.
This souled give you the solution for your issues that You experience now.
