Hello,
One tought or two between wake-up and leaving for work :-)

trunk/build_dir/toolchain-i386_gcc-linaro_uClibc-0.9.32/linux-2.6.37
 is kernel builddir. So, if it works from here, there's no reason it
finaly doesn't.

One tought: in "make menuconfig", you will setup the Openwrt's
package/features list. If you have one package marked "M", that means
it'll be build as separate package (*.opkg). If marked with "y", it'll
be integrated within FS image.

For you kernel module xen-pcifront, you have to make sure that:
- it's marked in trunk/.config
- it's marked in kernel config file

You can check after compliation:
ls -l build_dir/linux-x86_xen_domu/packages/ipkg-x86/kmod-xen-pcidev/
total 12
drwxr-xr-x 2 jbfavre jbfavre 4096 Mar  4 01:09 CONTROL
drwxr-xr-x 3 jbfavre jbfavre 4096 Mar  4 01:09 etc
drwxr-xr-x 3 jbfavre jbfavre 4096 Mar  4 01:09 lib
jbfavre@xps-103:~/openwrt/trunk$ ls -l
build_dir/linux-x86_xen_domu/packages/ipkg-x86/kmod-xen-pcidev/lib/modules/2.6.37/platform-pci.ko

build_dir/linux-x86_xen_domu/packages/ipkg-x86/kmod-xen-pcidev/lib/modules/2.6.37/platform-pci.ko

So, not sure you patch is mandatory, is it ?
