Kill useless pm_access from vt.c

Kill useless pm_access from vt.c

[Pavel Machek]

Hi!

pm_access does nothing these days, and looks ugly. This removes it
from vt.c. That actually looks like last user in the tree; it should
be possible to kill pm_access completely after 2.6.10. Ouch and add
warning to obsolete pm.txt file. Please apply,

								Pavel
