I'm not sure yet if it is really bad "virtual" memory. Could as well be
interrupts or virtual disk controllers, since data seems to change while
being read from disk. You could run a quick test by copying a file from
ramdisk to ramdisk, and see if md5sum changes.

I have seen similar problems in virtualbox with Linux guests using
recent-but-stable kernels quite often, ranging from freeze during boot
to random errors concerning all simulated hardware. I now use kvm for my
own tests, can't spend time much on debugging virtualbox. :-(

There seems to be a driver in the "staging" kernel section, which means
that the driver is quite new and not well tested yet, it may or may not
work with your card.

networkmanager should take care of starting wpa_supplicant as soon as
the card appears (test: "iwconfig", check for wlan0 or wifi0).

I just checked, there are a few modules which may work with the wifi card:
sudo modprobe rt2860sta
or
sudo modprobe rt2800usb
Now it COULD be that you need additional firmware. Please check "dmesg"
for any hint.
