Something must be looking at /proc/cmdline already or the installed grub.cfg 
wouldn't be including nomodeset in the default stanza.

Presumably mkconfig is using a default /etc/default/grub (<512 bytes). After 
finding nomodeset in /proc/cmdline, Anaconda could specify mkconfig use an 
alternate such file or perform some other magic to get the extra stanza 
included, maybe an /etc/grub.d/49_nomodeset.

Quiet is never in any of my Grub stanzas after firstboot.
