+Subject: [PATCH] Rework drm modules selection on ARM
+
+This is a wip version as plymouth still doesn't work for me
+
+1/ On arm, aliases use a different path (soc)
+2/ host1x has the matching device aliases
+ whereas tegra_drm has the crt_init symbol
+3/ Others ARM drivers may behave similarly
+4/ backlight and pwm_bl also need to be bundled.
+
+I'm currenly testing with fedora kernel 3.14 or 3.15
