Yes, though the chipset your laptop has will be somewhat important
(pciide controller, network card, etc).

Yes (for the OS running in dom0).

No (this may potentially get better with full support for xen2?)

Also missing, and relevant to laptops: cardbus/pcmcia and usb Xen, at
least as it currently stands, is so far mostly geared towards a server
environment. It will work just as well on a laptop, as long as you
treat your laptop mostly like a server :)

If your purposes are for experimentation with other OS's, test images
and so forth, you may wish to also consider qemu. (No reason you can't
use a bit of both).
