intel ips: CPU TDP doesn't match expected value

I get the following messages on v2.6.36-rc2-203-g502adf5:

intel ips 0000:00:1f.6: Warning: CPU TDP doesn't match expected value (found 25, expected 35)
intel ips 0000:00:1f.6: PCI INT C -> GSI 18 (level, low) -> IRQ 18
intel ips 0000:00:1f.6: IPS driver initialized, MCP temp limit 65535
intel ips 0000:00:1f.6: MCP power or thermal limit exceeded
intel ips 0000:00:1f.6: CPU power or thermal limit exceeded

(The last two messages repeat very often, one of them every five seconds; if I understand it correctly, that is normal and expected.)

The code implies the "CPU TDP doesn't match expected value" is a sanity check failing. Should that happen, or is there something wrong?
