I have a couple of aliases you might find useful for this:

alias rg='rpm -qa | grep -i'
alias yg='yum list | grep -i'

They're not terribly efficient, but I don't use them that often,
either.  Also, I have a setting in my .rpmmacros (or .rpmrc) file at
home that specifies to list the machine type along with the file name
- I can't remember it (or find it) right now, but I got it here, so
someone knows....

(Figures that I wouldn't have it here....)
