Poor performance of 3D Acceleration

I understand 3D acceleration is still experimental, but this information might help with anyone working in this area.
I am running a Windows XP host (SP2) 2.8Ghz P4, 2GB from 2004 vintage and an NVida GeForce4 MX 440 ... old ... ( with VirtualBox 3.0.10 r54097) and have experienced the following 3D performance with glxgears in a number of Linux guests:
All numbers below are for glxgears over 5 seconds (not FPS)
Kubuntu 9.10 Release, XOrg 1.6.4, 3D accel. enabled (this is the desired target VM'ed system) Kernel 2.6.31-14-generic
480 - without VBox Guest Additions
300 - with VBox Guest Additions (slowed down?)
630 after disabling the XP host video card acceleration
KUbuntu 9.10 Release, XOrg 1.6.4 and VMWare 6.5.3
660 after disabling the XP host video card acceleration
Mepis 8.0.10 Xorg 1.4.2, 3D accel enabled, no Guest Additions installed
860 Watching the XP processor loading in Task Manager and top in Linux, kded seems to causing a problem. Killed it.
Repeat last Mepis test, 3D accel enabled installed GA's
660 with kded running
900 after killing kded (again, slower with GA's installed)
800 after disabling the XP host video card acceleration
Comparison to VMWare 6.5.3 Mepis 8.0 3b Bagside precanned version, Xorg 1.4.2
1900 after killing kded (no apparent problems with kded in this distro before killing it), so improved just a bit
1700 after disabling the XP host video card acceleration
Debian Sarge - in-house version, kernel 22.214.171.124, XFree 126.96.36.199
1540 (have actually seen as much as 2000 on different days/test runs, but 1500+ typically)
1540 after killing kded
1300 after disabling the XP host video card acceleration
The VMWare sessions have very noticeably better window dragging. Mepis 8.0 can drag windows as fast as the host with no lag/blur. So the hardware can respond effectively.
What seems to stick out at the extreme's is XOrg 1.4.2 is ok under VMWare and XOrg 1.6.4 is terrible under VBox. Additionally the Guest Additions slowed down the tests and disabling the host acceleration improved performance in the first case. Something seems backwards here.
VMWare is certainly quicker than VBox, and XOrg 1.42 is seriously better than XOrg 1.6.4 (so is XFree, but obsolete), so the combination of VBox and XOrg 1.6.4 makes for a very mundane 3D performer.
I also tried real time kernel Kernel 2.6.31-9-rt with Kubuntu 9.10/VBox and it made no difference. Killing kded in Kubuntu 9.10 made no performance differences.
As there is no crash, I have not provided a log, but can on request if it would help.
