Yes, I just tried it. It works! and it fixes the button problem in 2.2.6.
I first tried one that did not work, but I've attached the one I did get to work. Just copy into /system/app, rename to Vending.apk, and change permissions.
Enjoy!
Or, you can just download and install it like any other apply. It'll install over the old Market no problem. It Indore you that it's a system apply, but works anyway.

Would this work ?
adb shell mount -o remount,rw /dev/block/mmcblk0p5 /system
adb shell cp /system/app/Vending.apk /system/app/oldVending.apk
adb push Vending.apk /system/app
adb reboot
