Have you tried something like -

yum install emacs locate ps3videomode

Lack of HDCP on a DVI monitor may matter on Linux, even though it
shouldn't.  I have heard that the PS3 wont even turn on the HDMI output
unless the monitor it's plugged into is HDCP compliant.  If this is
true, then a DVI to VGA adaptor wont help.  I'm going to be
experimenting with this quite heavily over the next two weeks on a
variety of monitors.  I'll let you know what I find.
