I (and others with acer aspire 5050series laptops) have a broken bios which resulted in kernel panic. Reported the bug http://bugzilla.kernel.org/show_bug.cgi?id=10237 and http://bugzilla.kernel.org/show_bug.cgi?id=8953 and a patch was written about it. Can/When will this be merged upstream? Any arguments against this as a hardware/platform solution?
