During test, I sometimes add/change boot parameters to /boot/grub/menu.lst (suse), or at the grub screen during boot.
How do I check what boot parameters have been used after the system is done booting?

The bootloader (grub in this case) will pass the boot parameters to the Linux kernel in a memory buffer called the kernel command line. The kernel command line, along with other console messages output during boot, should be in the system log, retrievable with the dmesg command.
A copy of the kernel command line is also in the file /proc/cmdline.
