Just finished an install of Ubuntu 8.04 Hardy Heron, and I'm seeing this same issue. The kernel is logging the following every six seconds:

Apr 27 21:28:58 sunshine kernel: [ 1353.176717] ACPI: Unable to turn cooling device [d9dcff18] 'on'

This is with kernel 2.6.24-16-generic. No updates have been released for Hardy as of this writing. (First time I've tried Linux on this hardware, so I don't know if issue presents on this hardware with older software.)

Hardware is an HP Pavilion a635w desktop, which uses an Asus A7V8X-LA motherboard with a VIA KM400 chipset. I've got the latest BIOS from HP installed. Power supply, chassis, and CPU fan are all spinning.

If I rmmod the "thermal" module, log messages cease; if I insmod it again they start up again.

No match for "PBLK" in any of the /var/log/{dmesg,messages,kern.log} files. In an eyeball review, nothing leaps out at me for an obvious cause, but I'm no expert at ACPI. I'll attach dmesg and dmidecode output. If there's anything more I can do to assist, please let me know.
