first of all: This is no problem for syslinux, it's a kernel issue. But maybe
we'll sort it out anyway.

Look at the kernel's output in the first few lines. It should say
Kernel command line: ....
and tells you what it really got. At least the 2.4 series does this.

Yes, there is, it's AFAIK 255 characters. I use quite long parameters regularly,
so 160+ characters work without problem.

That should have done it, according to ide.txt. Try ide2=noprobe ide3=noprobe,
maybe you confused the kernel by giving too much hdx and idex together.
BTW: Are you sure it crashes while initializing the IDE controllers, or could
it be that it crashes while initializing the next device, but didn't tell you that
it was already there?
