For msdos filesystem, there were a number of minor tweaks that were
made to make this suck less. Some were in the old usb layer, but most
were in the buffer cache of FreeBSD to make it more resilient to
errors from the device... But it wasn't totally fixed... Hans' stack
did have a period of time when card removal was working better than
the stock FreeBSD stack, but that got cleaned up before 7.0.
