Well, solo6x10 didn't use to have its own private ioctl's until now.
Still, that's strange, as there are other drivers also using vidioc_default.
I suspect that those _IO* have its highest bit equal to 1 on powerpc
being too big for int. If so, the enclosed patch should fix.
I'm still wandering why it didn't cause any compilation problems here.
Ok, I didn't try to compile it on powerpc, but still integers have 32
bits on ppc, right?
Anyway, could you please try the enclosed patch?

[PATCH] [media] ioctl numbers are unsigned int
