That's puzzling.

Can you describe the symptoms exactly ? What do you mean by "the kernel doesn't boot" ? Where and 
how does it stops booting ?

This commit only adds a new VDSO call, for getting y2038 compliant time. At the time I implemented 
it there was no libc using it yet. Is your libc using it ?

Where can I find all the elements you are using to boot with QEMU ? Especially the file 
MintPPC32-X5000.img

Can you also share you kernel config

Thanks
