Lowering the minimum region size does the trick.  Now my kernel says

hpet0: <High Precision Event Timer> iomem 0xfed00000-0xfed001ff on acpi0
hpet0: vendor 0x1022, rev 0x1, 14318180Hz, 3 timers, legacy route
Timecounter "HPET" frequency 14318180 Hz quality 950
Timecounter "ACPI-fast" frequency 3579545 Hz quality 900

With only 3 timers 512 bytes is enough address space.
