Possible workaround discovered...
It appears that ubuntu/kubuntu itself has an issue with this particular notebook (HP Compaq 6715s) as seen here:

This might mean that it has nothing to do with virtualbox, but read on...
So I have done some testing and here are the results. Using VirtualBox 1.5.6 with ACPI DISABLED and VT-x ENABLED, I have managed to start installation of Kubuntu 8.04 normally (no more BSOD) . I also tested same settings on same notebook with VirtualBox 1.6.0 and BSOD still appears...
I have no more time to explore is this strictly kubuntu problem and what to do with VB 1.6.0 but if someone has the time, this could be a good starting point...
I also updated bug ticket that I posted about this...
HTH
Vista Business + Kubuntu 8.04 = Blue screen of death
Ticket Closed, but VT-x required or display driver crashes?
VT-x is required still with the new DL3.5-RC4_211008.iso (Dream Linux 3.4 RC5 - http://www.dreamlinux.com.br/download.html) or the ATI video driver crashes.
VirtualBox 2.0.4 on

ATI Radeon X1200 (dxdiag reports 1598MB video ram???)

I have updated my display drivers using Catalyst 8.1 to v7.14 dated 9/23/2008 using the install found here:

I will check some other Linux distros over the next few days. I still have a few other things to look into, but I've tried just about everything discussed in both topics concerning this issue.
