Platform should be supported by Xen, though it's not implemented yet.
My reading of the spec is that

mode='delay' track='guest'       corresponds to timer_mode=0
mode='delay' track='wall'        corresponds to timer_mode=1
mode='catchup'                   corresponds to timer_mode=2
mode='merge'                     corresponds to timer_mode=3

Agreed.

They do not support it in <timer> though, do they?  They also support
pit for that matter, but they cannot do anything to customize it.
