@Grex:
This Czech Amiga News page suggests that the RsrvKick program was
available for Fusion as early as October 1998, together with a new
RsrvCold program and new video drivers!

As we have seen, the Fusion 3.2 upgrade was not available until March
2000.
Of course, it's possible that 'RsrvKick' is a mistake when 'RsrvWarm'
was actually intended. However, this is unlikely because news archive
entries are contemporary accounts and this predates the documented
appearance of the RsrvKick program by almost 2½ years!
Naturally, the download link to get this latest stuff is dead!
Methinks this requires further investigation...
[Edit] Haage&Partner's website gives March 1998 as the release date for Fusion Amiga 3.1
