Yes, latter I'd feel with the thing most against it that there aren't
actually many that need it. Here's the list that was posted:

http://lkml.org/lkml/2008/8/1/96

Three legacy ISA driver from that list can now be stricken. Hurrah.

There's always going to be at least a few that'll remain though. For
example, what are you going to do with:

--- linux.orig/drivers/ide/Kconfig
+++ linux/drivers/ide/Kconfig
@@ -9,6 +9,11 @@ config HAVE_IDE
menuconfig IDE
tristate "ATA/ATAPI/MFM/RLL support"
depends on HAVE_IDE
+
+ # my test box expects /dev/sda, not /dev/hda
+ depends on BROKEN_BOOT_ALLOWED
+ select BROKEN_BOOT if IDE = y
+
depends on BLOCK
---help---
If you say Y here, your kernel will be able to manage low cost
The hda->sda thing was just a disaster -- personally I have to remember
to change things around till this very day before I boot into my distro
kernel to test things. I wouldn't be the one suggesting a patch to
drivers/ide to "fix" that though including really a patch to its Kconfig
marking it as breaking anything in a global way rather than a
user-specific way as was done here.

Maybe the test boxes should always boot with ide_core.noprobe=<all> for
a suitable value of <all> or some such...

Others are the video ones. FB_VESA, FB_VGA16FB and even MDA_CONSOLE are
in there which seems to imply some decidly non-legacy hardware and I
sort of doubt willingness to assume global validity of such a setup.

But yes, there is value in the testing so perhaps still worh something
generic.

(I'll continue some specific looking through the list first although I
don't believe there is much else that really wants specific fixing).

Rene.
