Like it.

Makefie bits:
5 EXTRA_CFLAGS = -Iinclude/drm
Use ccflags-y := -Iinclude/drm
I assume this is a temporary workaround and you plan to fix
up all includes to use "#include <drm/fo.h>"

6 drm-objs := drm_auth.o drm_bufs.o drm_context.o drm_dma.o drm_drawable.o \
7 drm_drv.o drm_fops.o drm_ioctl.o drm_irq.o \
8 drm_lock.o drm_memory.o drm_proc.o drm_stub.o drm_vm.o \
9 drm_agpsupport.o drm_scatter.o ati_pcigart.o drm_pci.o \
10 drm_sysfs.o drm_hashtab.o drm_sman.o drm_mm.o

Use drm-y := ....

11
12 ifeq ($(CONFIG_COMPAT),y)
13 drm-objs += drm_ioc32.o
14 endif
So you can do:
drm-$(CONFIG_COMPAT) += drm_ioc32.o

Take the above as general input for all your Makefiles.
