FYI, thor2002ro posted one on the dev forum:
Just download the one that matches your specific Kernel (look in Settings - About tablet to see what you have running.)
On another note, I found that the default BusyBox and OpenVPN Installer's on the Market wouldn't quite work. Busybox installs at /system/xbin/ and I told OpenVPN to look for it there, but it REALLY looks for it at /system/xbin/bb/ so I created that directory, created symlinks for "route" and "ifconfig" in that directory pointing back to the /system/xbin/busybox executable.
For those not in the Linux know, at the adb shell you'd do:
ln -s /system/xbin/busybox /system/xbin/bb/route
ln -s /system/xbin/busybox /system/xbin/bb/ifconfig
