Parent "device" selection in kernel configuration

[Bexley Hall <bexley.hall%yahoo.com@localhost>]

Hi,

Hopefully the correct list for this question...

I'm looking for some guidance in deciding criteria that
affect your (i.e., *my*) decision as to which of (for
example):
    lpt* at acpi?
    lpt* at isa?
    lpt* at pnpbios?
to use in a particular (5.1.2/i386, in this case) kernel
config (and, of course, any other drivers that have a
"choice" of where they "attach" in the kernel config).

Said differently, if *all* of these will work on a given
box, how should one go about choosing *which* to rely
upon?

Are there performance differences between them?
Kernel size differences?
Boot time impact?

I.e., how does the code change (if at all)?

Thanks!
