Compile fails because _PAGE_KERNEL_EXEC is undelcared in alloc-r0drv-linux.c:138 There are several bugs which mention virtualbox-modules-1.6.6-r1 not compiling, but I did not see any mentioning this particular kernel. For instance, bug 266468 mentions a slightly later kernel linux-2.6.29-gentoo. That bug was marked resolved/fixed, though it was fixed by the user moving on to a modern version of VirtualBox, not by a patch, as far as I can tell. I was hesitant to unmask ~x86 of VirtualBox. I'm running a lesser OS prone to disease on it and I'm concerned it'll have to reauthenticate...again. Yeah, I know, forgive me; its for testing.

Hi, did u solve it. I have the same problem, thanks.
3.0 stable everywhere.
