[Bug 21558] Re: Thinkpad R31 requires 'i8042.nomux=1' on kernel commandline

[jerrylamos]

Thinkpad R31, 512 MB memory, feedback;

1. Was running well with Feisty and feisty workaround on kernel line: noapic acpi=off irqpoll
2. For feedback on 8.04, went to Ubuntu main site and downloaded fresh copy of Ubuntu on June 5.
3. CD got many failures as booted, could not even manage an install.  Suddenly it would get 11 false shutdown menus.  Unmanageable.
4. CD booted with i8042,nomux=1 did run, seemed to me the slowest install I've done.
5. Booted Hardy without changes on kernel line.  Ran O.K. so long as track point cursor stayed away from the borders.
6. Updates installed - 210 of them! on a fresh install!
7. Tried the noapic acpi=off irqpoll.  This worked on Feisty.  Hardy boot crashed.
8. Tried i8041,nomux=1.  Better behaved as far as cursor was concerned, however visibly slower on internet videos.
9. Conclusion: run with kernel as is, be careful.  On occasion, false shutdowns occur, but only one, easy to cancel.  Another common instance is the bottom border jumps to the top.  Position easily restored.

So I'm O.K. with running the kernel as installed, no added commands,
willing to take occasional erratic actions as a trade off on getting
faster internet videos.  Note System, Preferences, Appearance, Visual
Effects set to none.  I'm into applications not eye candy.

If Hardy changes to some default of i8042,nomux=1 for the R31, can I set
it to i8042,mux=1?  What would be the command?
