You could theoretically create a hacked kernel image that "looked like" the "secure" one for the applications, bypassing the Fritz chip completely, but I don't see the point. It's probably easier for the consumer just to skip the services that require DRM and stay in the "Open" mode.
No, not necessarily a hacked kernel, actually if it checks checksum right after bootloader that is gonna be a bit hard. Provided it doesn't use CRC32 for that.

We're not talking about the average consumer. Or, at least, I am not. I'm talking about a Maemo version of Jon Lech Johansen.

Since one can (theoretically) run the whole Maemo 5 OS on SBox, the hacker can indeed use a rootkit for QEMU. Once that is works its childs play to jailbreak the device. For example, spoofing or ignoring some system calls. MITM is also a potential vulnerability. Or one local hole in one of the bundled software.
