Usually your system logger keeps a copy of the kernel output - look into your /var/log/ directory and see if you find what you need there (e.g. /var/log/kernel/current if you use metalog).
If that doesn't suit your needs check out the kernel configuration option CONFIG_PRINTK_TIME in the "Kernel hacking" section. Hope that helps

this adds the ugly ticks that ubuntu has, I was looking for time and date...

You'll have to hack the kernel to do that...
I'm not sure when in the kernel startup sequences the date and time get read from the hw rtc - probably late in boot. Thus during initial boot, the kernel has no idea what time it is, thus it prints out relative time. If all of the dmesg output gets logged by syslog, won't syslogd timestamp it anyway?
