In my experience, the kernel arguments only affect -
1) how much vram is recognized by the OS as available for both console
video and XFree86 video, and
2) the resolution(s)/drivers for console video.
One of the offshoots of this is if the kernel doesn't recognize/support
your video card, but XFree86 does [= is the case for my box, might be
the case for you] you need to tell BootX to use ofonly (either check the
'No video driver' box or specify video=ofonly as an arg) . . . and then
rely on XFree86 to call the applicable driver. Sometimes you have to be
pretty explicit in the XF86Config file to get reliability established.
In my case, I need to set the resolution I want to define for linux on
the MacOS side, boot with video=ofonly, and then from the command line,
get a failsafe XF86Config file going via the video config utility
invoked from the console command line as root.
In YDL 3 (Sirius), it's > /usr/share/redhat-config-xfree86/xconf.py; the
redhat-stuff in /usr/share seems to drive most of the config functions
and most of them seem to work even in non-gnome/kde windowmanagers or
console command line environments. So I use xconf.py to generate a
failsafe XF86Config and then tweak it to explicitly define the BusID
where my vid card lives, and making sure there's a [drivername].o for
fbdev to detect and hand off to in /usr/X11R6/lib/modules/drivers/video/.
Section "Device"
Identifier "Videocard0"
VendorName "Videocard vendor"
BoardName "Generic OF compatible"
Option "fbdev" "/dev/fb0"
Driver "fbdev"
BusID "0:14:0"
EndSection
For you, this shouldn't be an issue, since IIRC video=platinumfb works
and is supported in YDL 3 (sigh, must be nice), but if it isn't and your
screen turns black after a couple dozen lines of activity info at boot,
you should probably do video=ofonly, get the BusID out of dmesg, and
rely on a failsafe XF86Config plus fbdev combo to hand off to
/usr/X11R6/lib/modules/drivers/video/platinum.o (I think that's the
path, I'm not in linux at the moment).

Good luck !
