[Fantu <fantonifabio@tiscali.it>]

i have kernel also 2.6.26-xen lenny but not boot, 2 different config with
2.6.32 from xen-stable.32 git, 2.6.31 from git also with blktap=y and 2
option sysfs_deprecated, all pv_ops boot but all with blktap problem...
/sys/class/xen/blktap0/dev and /sys/class/misc/blktap0/dev there aren't but
blktap there is always
i not found solution :(
