No, that one's harmless :-)

That one makes acpid (apparently) useless. The rest of the commit description
is:
To be prepared for /proc/acpi/event removal we export events
also through generic netlink interface.
Note that "also". The actual effect of the patch is "instead".
Adding the two removed lines (but removing the post-increment of the event
count) fixes this.
> 5740294: eeepc-laptop: Implement rfkill hotplugging in eeepc-laptop
Reverting this fixes the rfkill oops; things work correctly again. I don't
know why this appears to be needed, since things work fine without this patch
‒ both Fn-F2 and echoing to /sys/class/rfkill/rfkill0/state ‒ even when I
start up with init=/bin/sh and test directly from that shell.
(901; BIOS rev. 1808.)

That one also says "also" where it should say "instead" (not that it affects
me).
... oh yes, there's a long delay between output of these two lines during
boot:
input: ETPS/2 Elantech Touchpad as /class/input/input5
eeepc: Hotkey init flags 0x41
(not seen in .28 or .28.1; not checked later .28.*.)
Anyway, a patch for the ACPI reporting problems will follow this message.
