Looking at fb_set_var(), it is clear that pixclock cannot bet set to anything
(and really this field, by its name, is meaningless for a virtual frame
buffer): if info->fbops->fb_check_var is not set (as is the case for xenfb),
the user-mode supplied var is simply overwritten with the current settings. I
can't see anything wrong in the behavior of Xen here - Stefan, why do you think
that fb_set_var() must actually do *any* change to the current settings, if the
low-level driver knows the settings aren't meaningful (currently the assumption
in XFree86 appears to be that changes to the requested mode settings are done
by the kernel only if the low-level driver considers the settings wrong)?
