Looks like a good combination to me.
It'll be $5 over your $100 budget when you add in the shipping, but they will ship it all at once, if you order it all at once.
Once installed on your desktop K7S5A your new 1.35 volt AXMD 2200 FJQ4C Barton Mobile will automatically get a slight increase in Vcore, from 1.35v to 1.525v.
This is because any desktop BIOS 'reads' different voltage bridges (L11 for desktops, L8 for notebooks), and it also 'interprets' the same bridge cuts differently.
As you can see in the enhanced image from Newegg, below, the L8 bridges are cut exactly the same way as the L11 bridges, on your new 2200+
A 'notebook' BIOS will read those bridge cuts as 1.35v, and any 'desktop' BIOS will read it as 1.525v
So, depending on how good your PC133 SDRAM actually is, you may be able to run this new CPU, right out of the box, with no mods whatsoever, at
12.5x 142.7 = 1783.7 MHz = XP 2400+
12.5x 146.7 = 1833.7 MHz = XP 2400+ (probably your limit with SDRAM)
12.5x 150.0 = 1875.0 MHz = XP 2500+ (this 150/150 setting requires
an OC BIOS... there's no other way
12.5x 166.6 = 2082.5 MHz = XP 2800+ (you will probably need PC2700 DDR, unless your SDRAM is exceptional)
The above assumes good memory, capable of 166.6 on your K7S5A.
You'll find out, by experimenting, just how good yours is.
To go higher than this, you will need to cut / join some of your L6 bridges, which correspond to the L3 bridges on a 'desktop' CPU.
But lets leave that until after you're up and running, and know what your memory is capable of, because, for now, it'll be your memory that is the limiting factor.
