I did not load it to check if tap2:tapdisk:aio and tap:tapdisk:aio
were the same or not.
This ( http://wiki.xensource.com/xenwiki/blktap2 ) wiki page tells I
have to use tap:tapdisk:aio in order to use blktap2 but it is wrong!

No, it doesn't. I'm using ext3 and I cannot install the bootloader, so
HVM becomes useless and I have to switch to PV (which is what I will
use for linux, but now I'm just testing). Is there any chance to
install the bootloader and so use HVM?

Uhm.. I'm pretty sure I never did it with debian stable, maybe
debootstrap did it for me?
