ztdummy on kernel 2.6 has tw implementations:

with USE_RTC defined (the default on x86, at least) it uses the rtc
clock of the system. This is availble on x86 and amd64. I don't know if
other architectures have anything equivalent.

Without it, it relies on HZ=1000 . That was the only possible value up
until 2.6.13 , so I guess that in the specific kernel you refer to it
should hold.

Most other modules are PCI cards. Two others are USB. I don't know how
much architecture-specific are PCI and USB.

There are also ztdynamic and friends. In theory nothing prevents them
from being portable.
