VBox 2.2.2 hosted on Gentoo/Gentoo guest - console scroll

[lyallp]

I have an install of Gentoo Linux x86 32bit inside VirtualBox OSE 2.2.2, which is hosted on Gentoo Linux x86 32bit with Linux Additions installed.

The problem is that the 'console', as it scrolls up, eventually starts going really slowly, jamming up the whole VM (or at least giving that impression).
It appears I can postpone this problem by booting into single user mode and clearing the screen (ctrl-L), thus, preventing scrolling.

I also have an instance of kubunto 9.04, but I don't know how to switch to the console session (ctrl-alt-F1) without my host responding and switching to my host console. Advice on how I do that would be appreciated, along with advice how I can send meta keys to the guest without the host interpreting it. (for example, I use fluxbox and alt right click re-sizes windows - if I do this, the VM Window resizes, not the window inside the guest).

I don't seem to have any problems at all with Windows guests.

I was wondering what settings I need to supply to assist in diagnosing the problem.

Here is a start

For the Host:
gentoo kernel 2.6.28 compiled with gcc 4.3.2
Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz
4GB memory
Virtual disk storage on ntfs-3g filesystem.
Host kernel config attached

The Guest:
512mb base memory
128mb Video memory
acpi enabled
io apic disabled
vt-x/amd-v enabled
nested paging enabled
pae/nx enabled
3d acceleration enabled
1 ide primary hard disk (15G)
Audio ALSA Audio Driver for controller ICH-AC97
Network PCnet-FAST III (NAT)
Gentoo-install-x86-minimal-20090422.iso install
grub boot parameters "video=uvesafb:1024x768-32@75,mtrr:3,ywrap"
Guest kernel config attached.

Any assistance is greatly apprecated.

The Guest:
grub boot parameters "video=uvesafb:1024x768-32@75,mtrr:3,ywrap"

dont know gentoo at all, but what is this framebuffer good for in the guest?

instance of kubunto 9.04, but I don't know how to switch to the console session (ctrl-alt-F1) without my host responding

[host-key]+[F1] where host-key usually is the right [ctrl]

Regarding right-ctrl F1, that worked, thanks, I was pressing right ctrl, alt, f1, which my host interpreted.

I was using the framebuffer to make a larger console.
Turning off the framebuffer does fix the scrolling problem, now I am back to 80x24.
80x24 annoys me. Maybe I should do it another way?
