There's a neat device called the BIOS Saviour which I first saw on the eksitdata site, http://www.eksitdata.com/, but which has now had a few reviews on English-language sites, e.g. http://www.alltechbox.com/reviews/ioss_rd1_bios_savior_eng.php3 and http://www.ascully.com/modules.php?name=Reviews&rop=showcontent&id=178. It consists of a mezzanine board that fits underneath your existing BIOS chip and contains a second BIOS chip that can replace the existing one. You can switch between the two via a switch mounted on a blank plate in an expansion slot. The intended use is to protect against bad flashes or virii (other uses are for hot-chipping motherboards with hacked overclocking-enabled BIOSes if the existing BIOS doesn't support it), but it could also be quite useful to swap out a TCPA-crippled BIOS for an unencumbered one . Really adventurous modders could set it up to boot into the TCPA BIOS as far as is necessary, halt the CPU via a small processor sitting on the SMB, swap in the non-TCPA BIOS, and continue.
