In 2.4.4, drivers/net/aironet4500_card.c has
# grep udelay linux/drivers/net/aironet4500_card.c
udelay(1000);
udelay(100);
udelay(10);
udelay(100000);
udelay(200000);
udelay(250000);
udelay(10000);
udelay(10000);
udelay(1000);
udelay(1000);
udelay(10000);
But on ia32, you cannot use more than 20000 for udelay (). You will get
undefined symbol, __bad_udelay.

I am not a kernel expert. You should ask it on the kernel mailing
list.

mv driver.c driver.c~
sed 's/udelay\( *\)(\([1-9][0-9]*\)000)/mdelay\1(\2)/' <driver.c~>driver.c
...keeps foo(...) or foo (...) as per original author's taste.
