Flash support under qemu seems to be about the same as CD-ROM support.  
That is, you can access a device present at start up but it's not 
swappable.  Given:

[dave at bend ~]# lsusb
Bus 001 Device 002: ID 154b:0005 PNY
Bus 001 Device 001: ID 0000:0000 
Bus 002 Device 001: ID 0000:0000 

you can attach the device to a W2K qemu session by starting qemu with 
something like:

qemu -usb -usbdevice tablet -hda w2k.img -usbdevice host:001.002 -m 256 
-localtime &

I tried swapping two different 1GB thumb drives and the content of the 
drive wasn't visible after the swap.

If you decide to go the qemu route for a VM with W2K, I wrote about the 
problems I ran into on my blog at:

Getting a basic W2K VM working was fairly easy but getting it fully 
updated was a real pain.  I still have a couple of MS updates that I 
can't apply since W2K stops working if I do.

Cheers,
Dave
