Installer & Kickstart options to disable hi-res video modes

Got burned by this on RHEL6--the default to allow the kernel to use high-res text & graphics modes is nice on desktop/laptop hardware, but backfires big-time with data center equipment like ancient (7-year old) KVM switches & RAC/ILO-type server interfaces that can't grok (or simply doesn't have the network bandwidth to handle) the super-high-res modes that newer server hardware video chips support.  I know there is a kernel boot param that can be added to disable that, but the Installer itself should be thus limited by default _and_ should have a check-box + kickstart option to disable it from the git-go when installing systems.
