we ran into the same problem sometime back as we use 32 bit OS. we achieved sga sizes as high as 3 gb by rebuilding the oracle kernel.these steps are for solaris 2.6 running 8i ..

these steps have been shamlessly copied from metal link .. excerpts follow ....enjoy ...

The steps to configure the sgabeg are as follows: 1. Shutdown any databases
2. Make a backup copy of 'libserver8.a'

	% cd $ORACLE_HOME/lib
      % cp libserver8.a libserver8.a.orig

3. Generate the "ksms.s" file (change the address at which the SGA attaches. see below for complete map)

% cd $ORACLE_HOME/rdbms/lib
% $ORACLE_HOME/bin/genksms -b 0x30000000 > ksms.s
4. Regenerate the 'ksms.o' object:

    % make -f ins_rdbms.mk ksms.o
5. Archive 'ksms.o' into 'libserver8.a'

    %ar r $ORACLE_HOME/lib/libserver8.a ksms.o 6. Relink

% make -f ins_rdbms.mk ioracle

Following is the address chart for configuring the sga beginning address according to the max sga size required.

sgabeg = 0xe0000000 | 256Mb SGA 
sgabeg = 0xd0000000 | 512Mb SGA 
sgabeg = 0xc0000000 | 768Mb SGA 
sgabeg = 0xb0000000 | 1Gb SGA 
sgabeg = 0xa0000000 | 1.25Gb SGA 
sgabeg = 0x90000000 | 1.5Gb SGA 
sgabeg = 0x80000000 | 1.75Gb SGA 
sgabeg = 0x77000000 | just less than 2Gb SGA 
sgabeg = 0x70000000 | 2Gb SGA 
sgabeg = 0x60000000 | 2.25Gb SGA 
sgabeg = 0x50000000 | 2.5Gb SGA 
sgabeg = 0x40000000 | 2.75Gb SGA 
sgabeg = 0x30000000 | 3Gb SGA 
sgabeg = 0x20000000 | 3.25Gb SGA 
sgabeg = 0x10000000 | 3.5Gb SGA 
sgabeg = 0x01000000 | 16Mb less than 3.75Gb SGA
