kernel compile questions

i just compiled a kernel, by using the config of the installed one 
(2.6.33.7-2mnb and making the serial driver for 8250 into a module rather than 
built in (i'm having probs with my serial ports)) and the result is an rpm  
227mb in size, is that normal? and in trying to install it, i get the message 
that i need 121mb in / , despite having over 1.4gig spare in / . and 400mb 
spare in /boot . is this a familiar issue to anyone?

bascule
