ACPI messages in syslog

Well, I have to say I've had just about enough of ACPI.  This last time 
it nearly corrupted my entire hard drive.

Here's my problem:

For some bizarre reason the newer Fedora versions (from 7 onward), the 
ACPI implementations refuse to play nice with my CPU fan (or my PS fan, 
I cannot say which, /other/ than it's a fan).  So, I have posted a 
couple of times about these errors being logged in syslog and got no 
answer, so I figure not using ACPI is fine.  It leaves my fans on all 
the time, but hell, it's just money, right?

Now the problem is kinda sorta rearing it's ugly head again.  Even with 
'noacpi' as a kernel option, I'm still getting thousands of 'ACPI: Can't 
turn fan device to off' or similar being dumped into syslog after about 
4 or 5 hours of this system being on.  At a certain point syslog fills 
up my hard drive (/var is on /, I never expected this to be a problem) 
and bombs my system.

The last time this happened (last night) it corrupted / on my primary 
HDD and I had to fsck it manually.

So, after a good therapy session, I'm calm enough to find out the 
answers to a couple of questions:

1.  Is there any way possible to stop ACPI from logging these blasted 
messages, especially when I have 'noacpi' as a kernel option?

2.  If that's not possible, is there anyway to make rsyslog STOP logging 
at a certain size for /var/log/messages?

3.  Is there any other bleeding way around this so I can stop worrying 
about this silly problem?
