Whatever you mean by kmp'd game, the answer is no, there is no way to bypass anything on the ps3. Part of the firmware is encoded in the hardware, either on one of the spe's or the ppc core. The firmware, and thus none of the games, will not run without it, and it will not run any firmware but sony's.
OtherOS doesn't provide any loopholes either as it is simply an emulated environment, with the firmware and hypervisor firmly in control.
Because of this it is utterly impossible to modchip or soft-mod your way around the optical copy-protection. Especially since any successful mod or workaround or hack would become known to Sony long before it reached much of the public, and the firmware would be quickly updated to ban every affected ps3.
A successful mod would probably have to involve custom firmware, which is nearly impossible to make because you'd have to reverse engineer the hypervisor to figure out exactly how it works... even then it's difficult to come up with software to actually run the thing. How that's done is a Sony trade secret, just as the mysterious workings of ATI and Nvidia cards are trade secrets. I don't remember a fully-function open-source driver for literally any ATI or Nvidia card. (there are open source drivers, but not fully functional like the legacy drivers)
