Yes, /boot/kernel.i915 contains the new kernel. I use UEFI boot, grub has always been really hard to setup on this machine. I used this bit you quote from the page to try to boot into the kernel: # nextboot -k kernel.i915 reboot But this is making me think it really didn't work because that's the wrong diredtory that it is loading i915kms from, and I think we're looking for i915.ko anyway -- which isn't listed at all. $ kldstat -v|grep i915 44=A0=A0=A0 1 0xffffffff8248d000 6c2bb=A0=A0=A0 i915= kms.ko (/boot/kernel/i915kms.ko)=A0=A0 =A0=A0=A0 =A0537 vgapci/i915kms I'll try to find more info on booting an alternative kernel with PC- BSD and UEFI.
