hwclock/rtc ongoing issue

[Matt Mercer]

Hi All,

I have found atleast one other person whos system uses an ALi 1533/1535
southbridge that is also experiencing the lockup when hwclock hits the 
rtc device.

I am still trying to work out a scheme to debug the system, but perhaps knowing
the hardware commonality will help some.

Interesting note, my chip is actually an ALi 1535.  The datasheet on this chip
states the PCI ID is 0x1533. Guess the ID wasn't bumped during early 
generations.

Will post more information as I discover it.
