Obviously, the data structure "file_operations" has changed. The same thing happens, when compiling recent {v >= 173} nvidia-drivers in the same environment. For the nvidia-drivers, there exists a patch [for nv.c, around line 426], that makes them at least compile. There are several tickets {eg. http://bugs.gentoo.org/show_bug.cgi?id=336837}, describing this. A similar solution could be searched for kqemu.

Looks like the "error: unknown field 'ioctl' specified in initializer" problem that has been plaguing out-of-tree modules.
Created attachment 258828 [details, diff] Proposed patch for kqemu-1.3.0_pre11 Here is a proposition of a patch, same fix as in bug 342161 comment 6 (it replaces .ioctl by .unlocked_ioctl in struct file_operations) It makes the module compiling, but I have not tested the module yet.
Created attachment 274387 [details, diff] Improved patch for unlocked_ioctl Here's an improved patch to use the unlocked_ioctl file operation, based on kqemu-1.4.0_pre1 sources but with a related fix for 2.6.39 (see bug 368439). Note that for kernel version 2.6.37 and later, the init_MUTEX patch is also required - /usr/portage/app-emulation/kqemu/files/kqemu-1.4.0_pre1-init_MUTEX.patch
Still valid with 1.4.0_pre1-r1?
kqemu is masked for removal so this will not be fixed.
