Partioning for a FBSD-64 install

Mon Sep 27 08:54:06 PDT 2004

1.  Is it my imagination or is a 64 bit install going to take twice the 
space of a regular 32 bit one?
2.  I have seperate SCSI drives, one for XP-64 and one for FreeBSD-64. 
In the past I have used grub to boot between OS's.  If #1 is true 
    then grub will no longer be on  a floppy and will have to become 
bootable CD unless useable in emulation mode.  Is there a grub port for 64?

Thanks,  Rob.
