Errors in error.log – possible fixes?

Question

I have now completed my home server with arch linux, and get everything working like i wanted. :-)
Now i have found some messages within the error log i couldn't find a solution for. It looks like nothing important to me, they sound more like informations than actual errors, but maybe there is some configuration wrong and can be fixed to avoid these messages.
The first one
SP5100 TCO timer: mmio address 0xb8fe00 already in use
occurs during udev on each boot. (I'm running kernel 3.2.8-1-ARCH)
dhcpcd[553]: eth0: sendmsg: Cannot assign requested address
I configure the network via DHCP, and the router decides the ip according to a mac-address/ip-address-look-up-table. I think dhcpcd tries to decide the ip-address in the first place, and fails until the router sends the correct one.
/usr/sbin/crond[613]: (CRON) INFO (Syslog will be used instead of sendmail.): No such file or directory
This is obviously because I don't have sendmail installed. Can I configure cron to use Syslog instead of sendmail? So it doesn't checks for sendmail everytime it is started.
Thanks!

Answer 1

@skanky,
Is it possible that we are using different implementations? That is, I'm using cronie but dcron also provides crond.
From man crond:
SYNOPSIS
crond [-n | -p | -s | -c | -m<mailcommand>]
crond -x [ext,sch,proc,pars,load,misc,test,bit]
and:
OPTIONS
-m This option allows you to specify a shell command to use for sending Cron mail output instead of using
sendmail(8) This command must accept a fully formatted mail message (with headers) on standard input and
send it as a mail message to the recipients specified in the mail headers. Specifying the string off (i.e.
crond -m off) will disable the sending of mail.
-n Tells the daemon to run in the foreground. This can be useful when starting it out of init.
-p Allows Cron to accept any user set crontables.
-c This option enables clustering support, as described below.
-s This option will direct Cron to send the job output to the system log using syslog(3). This is useful if
your system does not have sendmail(8), installed or if mail is disabled.
-x This option allows you to set debug flags.
