$ gcc -v
gcc -v
Reading specs from /usr/lib/gcc-lib/i386-linux/2.95.4/specs
gcc version 2.95.4 20010810 (Debian prerelease)

... I saw the same problem as I did when using the gcc-3.0.5 compiler.
Here's my transcription of the kernel output when poking around
with the disks ...

ALI15X3: chipset rev 32

ide1 at 0x170-0x177, 0x376 on irq 15
hda: 6303024 sectors (3227MB) w/128 kiB Cache, CHS=781/128/63 (U)DMA
hdc: 16514064 sectors (8455MB) w/512 kiB Cache, CHS=16383/16/63 (U)DMA

at this point there are again the messages about ide_dmaproc and
then the "drive not ready for command".

I have an old 2.2 Debian kernel that I booted from, and it has
the driver in it. Here is it's output, if that is of any use ...

As for the question about the drive being disabled in the BIOS, if
I read you right then the answer is no, the drive is not disabled.
Otherwise I couldn't boot up. As for the settings of things like
DMA, 32-bit mode, etc, I can set much of them with hdparm, though
DMA I could not do, and I've poked around the BIOS configuration
screen looking for what to set, and have come up empty. The BIOS,
BTW, is 'AMIBIOS 8/28/1997 S' and the motherboard has a
"TXpro Pentium PCI" chipset and supports Ultra DMA/33, according
to the manual that came with it.
