I've always (well, after switching to partitions) used something near
80mb, for the last servers using ~ 160mb
root@kappa2:~# parted /dev/cciss/c0d1 print free
Model: Compaq Smart Array (cpqarray)
Disk /dev/cciss/c0d1: 1000GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start   End     Size    Type     File system  Flags
 1      16.4kB  1000GB  1000GB  primary
        1000GB  1000GB  168MB            Free Space
