Well, I'll forgive everyone for not jumping right in and flooding me with 
answers to this one. :-)  Thanks to the quick wit and brilliant insight of 
Petr Vandrovec (the author of matroxset and the matrox fb code in the kernel) 
we discovered that, because I'm using a single-head G400 with the dual-head 
add-on card, the matroxfb_maven.c file had to be tweaked to find the right 
device on the I2C bus.  The line
	#define MAVEN_I2CID     (0x1B)
had to be changed to
	#define MAVEN_I2CID     (0x1A)

Making that one-character change and rebuilding the kernel fixed all my 
problems.  I don't know how common this problem is (not too, I'd guess), but 
hopefully this will help someone else out!

Thanks,
B
