Are your sure you got it right?
You can for example look for the reset/irq vectors at the start... there should be several B 0xXXXXXXXX instructions at the start of the bios.
And, there should be a exact copy of the Nintendo logotype somewhere in the BIOS. (the stuff stored in the header on every game)

I am 100% certain that my BIOS image is accurate (I have even been able to use it and boot ROM with BoyCott Advance).
So far, I spotted some vector address changes for the Reset, Software interrupt and IRQ, and also some instruction changes at some points.

Not sure why no-one's replied.
Perhaps I'm not supposed to say?
Some BIOS's floating around must have been dumped
from earlier versions in development equipment.

You can hear the difference between the BIOS floating around on Kazaa (which may have been dumped from a devkit) and the release BIOS in the logo sound. On the common Kazaa BIOS, you'll get a Cmaj9 arpeggio on a piano-like instrument and then a plain da-ding reminiscent of GBC. On the release BIOS, you'll get an Fmaj9 arpeggio with smoother reverberation and then a fancier da-ding with two voices an octave apart.

Most likely your dump is good -- there was an early version of the BIOS that was distributed on the newsgroups/gnutella/etc, etc, etc. I don't know if there is anything wrong with it, but it's obviously not the release version.
Here is the checksums for the BIOS -- I dumped this from my own machine, so I know this is the correct version:

No doubt this is covered elsewhere on the board, but there were at least two hardware versions of the original GBA before the SP was released. I modified my original style GBA with the "TV de Advance" video-out mod and when it first arrived the cable didn't fit.
I can't imagine the two different versions have the same BIOS. I would imagine there are at least a couple of BIOS versions for each hardware version. Since the GBA is a closed system, so long as the official instructions behave the same, Nintendo aren't worried about changes to undocumented stuff -- in fact it helps deter unwanted (by Nintendo) hardware developments that might aid piracy.
