Randy, this is what the help switch says:
$ uname --help
Usage: uname [OPTION]...
Print certain system information. With no OPTION, same as -s.
-a, --all print all information, in the following order:
-s, --kernel-name print the kernel name
-n, --nodename print the network node hostname
-r, --kernel-release print the kernel release
-v, --kernel-version print the kernel version
* -m, --machine print the machine hardware name
< * Wouldn't this imply what the CPU is?>
-o, --operating-system print the operating system
--help display this help and exit
--version output version information and exit
My system has an AMD K6-2 processor, which is considered i586:
$ uname -a
Linux pmbent1 2.6.10-5-386 #1 Fri May 20 13:52:48 UTC 2005 i586 GNU/Linux
It would appear that I am using the generic i386 kernel. No mention of
an i586 kernel when I look in Synaptic with all the possible source
mirrors activated. This box is important enough to me that if anyone
knows how to get a current Ubuntu i586 kernel for Hoary (without
recompiling), I would greatly appreciate knowing where. Whenever I have
been able to acquire one in a Linux distro for this box, I've noticed a
difference in performance.
