Re: updated kernels / miata sound?

Fixed kernel sources have been prepared, but it doesn't appear that

sort of firmer timeline.
Neither my memory nor a quick google search turns up any promising
hits over the past year. You would probably need to run this
question by debian-kernel as well, since they're the ones
responsible for kernel maintenance -- you might also want to
provide more information about the specifics of your sound
hardware, as I don't know if a reference to Miata will tell them
any more than it told me.
Sorry, I assumed it'd be common knowledge on the alpha list as to
what sound hardware the Miata has ;) - apologies. Its ES1888, using
the snd-es18xx ALSA driver. I ran some kind of sound setup utility
(whose name I cant remember right now - a debian user told me of it -
might have been alsaconf) and it setup /etc/modprobe.d/sound for me,
though I changed it slightly to follow the settings given in:
Which was a question posted to debian-alpha on whether anyone had
gotten miata sound working with 2.6.
My /etc/modprobe.d/sound file contains:
options snd device_mode=0660
alias snd-card-0 snd-es18xx
alias sound-slot-0 snd-es18xx
options snd-es18xx enable=1 isapnp=0 dma1=1 port=0x220 irq=5 dma1=1 dma2=5 mpu_port=0x330
install snd-es18xx /sbin/modprobe --ignore-install snd-es18xx && /usr/lib/alsa/modprobe-post-install snd-es18xx
However, modprobe snd-es18xx results in an oops (register dump
trimmed for brevity):

The modules are loaded though, however sound does not work

Tyson Whitehead replied to the above mentioned debian-alpha post
about 2.6 es18xx problems on alpha with:
Pointing out that ISA is currently broken on Alpha and referencing
patches of his needed to allow ISA devices to work (alpha-isa.patch),
as well as an es18xx alsa patch to alleviate skipping problems
So what I'm wondering is, what's the status of these patches? If
they're known to fix problems could they be included in alpha builds
until such time as these problems are fixed upstream?
You pointed me at debian-kernel, so presumably I should post my
questions there.. Cc'ing with this mail.
