I have a 64-bit machine and latest release and get the lower $MaxNumber
{$System, $Version, $ReleaseNumber}
{"Mac OS X x86 (64-bit)", "8.0 for Mac OS X x86 (64-bit) (February \
23, 2011)", 1}
$MaxNumber
1.23343371298165049042187866640855160387`15.954589770191005*^323228458
Verifying that this is the limit
2 $MaxNumber
General::ovfl: Overflow occurred in computation. >>

Whereas on the same machine with v6
{$System, $Version, $ReleaseNumber}
{"Mac OS X x86 (64-bit)", "6.0 for Mac OS X x86 (64-bit) (May 21, \
2008)", 3}
$MaxNumber
2.09311732226991365866275244680916044235`15.954589770191005*^646456781

Perhaps you have Home Edition of Mathematica. Until the most recent release (8.0.1, released just a few days ago), Home Edition included only 32-bit versions of Mathematica.
