I have no smart ideas straight away - just an observation: i keep testing
CONFIG_X86_ELAN=y on real hardware, and it's enabled in about 4% of my configs:
sirius:~/linux/linux2/configs> grep -h MELAN * | sort | uniq -c
358 # CONFIG_MELAN is not set
15 CONFIG_MELAN=y
and i booted a few recently:
sirius:~/linux/linux2/configs> grep -l MELAN=y *
config-Mon_May__2_13_30_09_CEST_2011.good
config-Mon_May__2_15_02_43_CEST_2011.good

config-Sun_May__1_22_15_02_CEST_2011.good
config-Tue_May__3_14_45_15_CEST_2011.good
(Note: CONFIG_X86_ELAN got renamed to CONFIG_MELAN recently.)
So whatever the breakage is, it's not just some 'nobody tests CONFIG_MELAN=y'
easy breakage, but possibly something more configuration (or test) specific.
Thanks,
Ingo
