44 functions for 2.5.67.
45 functions for 2.5.68
41 functions for 2.5.69
36 functions for 2.5.70
32 functions for 2.5.71

Five less, one more. The newcomer this time is in
0xc0b9c9a0 isd200_action: sub $0x444,%esp

This is curious, since no obvious change causing this is in the 2.5.71

The two big consumers on the stack are these two, that use a little
over 256k and a little over 512k respectively.
        struct scsi_cmnd srb;
        struct scsi_device srb_dev;

This one really puzzles me, as those two variables were already present
in 2.5.67. A closer look reveals that the function isn't exactly new,
just oszillating around the 1k limit.

0xc08c0be3 <isd200_action+3/1ac>: sub $0x16c,%esp
2.5.64 - 2.5.67: <1k
0xc0b73c60 isd200_action: sub $0x424,%esp
0xc0b4bea0 isd200_action: sub $0x414,%esp
2.5.70: <1k
0xc0b9c9a0 isd200_action: sub $0x444,%esp

Quite an interesting behaviour that I don't fully understand yet.

If you're willing to restrict the flexibility of your approach,
you can almost always do something better.
