Problem with speed and resolution on Linux guest

Hi,
I have problem with slow guest system. I'm using virtualbox 2.04, host system is win XP. Guest system is Archlinux (fluxbox) and system-response is very slow. When i'm scrolling in webbrowser or starting some programs, it takes very long time.
My friend has same problem with Kubuntu (as guest system, win xp host), even he can't change any higher resolution than 800x600. We both have guestadditions succesfully installed. I can't also change my depth of color to 32bit., because then Xorg server doesn't start a makes an error.
Does anybody have similar problem as we? Do you have any solve? Thanks for help.

Same problem with gentoo, going back to 2.0.2 solved it.
It also seems there is a memory leak in 2.0.4, and a pretty big one, takes only about 15 minutes to eat all of my memory and it doesn't free it even after I completely close VirtualBox (again no problems with 2.0.2).

That memory leak is strange, as it was reported to exist in 2.0.2 and Vista. It's solved in 2.0.4.

As for the colours, setting Linux to 24 bit colours is the same as the Windows 32 bit.
For the Resolution, you have to install the Guest Additions to be able to use custom resolutions.

Don't know if they fixed the leak in Vista, but they sure introduced a new one in XP.
As for the resolution, as the previous poster already said, the guest additions are installed (and successfully loaded, I checked that), and xorg.conf is correctly configured. Unlike Hans999 I can at least change the resolution after I log in, but it always starts at 800x600), no matter what I put in the configuration files.
I know about the color depth, but I understand that it's a bit confusing for users coming from Windows.
